  Uplink Ports Fibre Channel

  Manage ports Uplink Fiber Channel FCoE traffic between the interconnection of fabric and the next layer of the

  SAN storage network. All FCoE network-related traffic is pinned to one of these ports.

  By default, the Fibre Channel ports are uplink. However, you can configure them to work as Fibre Channel

  storage ports. This is useful in cases where a Cisco UCS requires a connection to a DAS storage

  Device (DAS).

  My question is, how the FC Port could handle FCoE traffic? My understanding was that FCoE will be lifted and Enthernet connection only.

  The CF module interconnection fabric is the place where the speration of CF vs. FCoE happen, so it's where the FC frame is extracted in the Ethernet frame.

• can I use both optical and fiber sfp modules?

  Hello

  I have 2 stacked 3548 P PowerConnect switches. The top switch got uplink fiber of 1 MM (G1) to another switch in a different building. If the top switch has 1 free uplink port and the lower 2 switch free uplink ports. Recently, we bought 2 servers Poweredge R620 and I would like to connect them to the Gigabit ports. The 'normal' switch ports allow only 100 Mbit/s, so I plan to buy 2 modules SFP 1000Base-T (for copper) to connect to them.

  Is this feasible? Can I use G2 on the top switch for SFP 1000Base-1 T? Is this allowed?

  Kind regards

  Erik

  Yes, it's quite feasible. The connection will be configurable the same 100 Mbps ports. Here is a link to the part number for the 1000Base-T transceiver.

• For Fast Ethernet SFP modules

  Hello

  We are looking for fiber-to-ethernet converter.

  Is there any SFP module that plugs directly into the Fast Ethernet to a switch port.

  Please visit the following link: -.

  http://www.Cisco.com/en/us/prod/collateral/modules/ps5455/ps6578/product_data_sheet0900aecd801f931c.html

  He said "the Cisco100BASE-X Form Factor Pluggable SFP (Small) (Figure 1) is a hot output device that plugs into the Fast Ethernet ports, dual rate Fast/Gigabit Ethernet ports or Gigabit Ethernet from a Cisco switch ports or a router, which connects the port with the fiber cabling network.".

  If this module can be plugged into any port of FE, is it compatible with Cisco switches only?...

  Please reply,

  Thank you

  Amit

  The SFP port is just a place where the optical SFP is sitting in the switch (connect internally to power, data bus, etc.). SFP offers you the possibility to install a plug-in to adapt to the requirement of the network; If short-range fiber, fiber long reach or same RJ45 without changing an entire line card or switch.  SFP ports are integrated in the switch by a manufacturer, not bolted on after.  The specification for the connector module and SFP interface is detailed in an SFP MSA (multi-source agreement); designed to offer a platform in the industry to build.

  If your switch has a fixed electric port and you do not have access to power (for a converter to media or other), then the terminal switch will be replaced by a device with a fiber interface option. That, or you'll find a power on fiber system with enough power to drive a Media Converter (which I don't think that there are still).

  I hope this helps!

• trunk fiber 3750 and 3850

  I currently have two 3750's (bunk). We recently bought two new 3850's and have stack as well. My question is, how to I master them? I want to be able to use the new switches with the same VLAN and IP addresses as the existing. The new switches are in the same basket as existing ones.

  The current 3750 are the gateway to my network (and they remain such, for now).

  I plugged an uplink to switch fiber as in:

  3750 (IG 1/0/49)--> 3850 has (IG 1/1/1)

  3750 (IM 2/0/49) b--> 3850b (IM 2/1/1)

  I gave the fiber ports the following parameters:

  3750 a:
  int item in gi1/0/49
  trunk program dot1q switchport
  switchport trunk allowed vlan add ALL
  switchport mode trunk
  switchport nonegotiate

  3750b
  int gi2/0/49
  trunk program dot1q switchport
  switchport trunk allowed vlan add ALL
  switchport mode trunk
  switchport nonegotiate

  3850a / 3850b:
  Item in gi1/1/1
  Gi2/1/1
  switchport trunk allowed vlan add ALL
  switchport mode trunk
  switchport nonegotiate

  At this point, I thought I'd be able to ssh in the new (3850) switch and ping current (3750), but I can't. Assistant network on the switch curent 3750 'sees' the new 3850, but has he appears as "unsupported device". The switches are on the same subnet (10.11.1.0/24).

  Tandem switch (3750) is 10.11.1.2 and new 3850 is 10.11.1.14. If I connect my laptop on the 3850 and give me an IP 10.11.1.x, I ping the switch itself (10.11.1.14), but I can not ping to the gateway (10.11.1.2). If I SSH in switches, I can not ping each other.

  Do I need to set up the uplink fiber as an Etherchannel? Or are my settings incorrect switchport? I don't know what I'm missing. I'm certainly not an expert in the field, even if its something that may be obvious to others, it's quite possible I forgot.

  Hope it makes sense. Any suggestion would be appreciated. Thank you.

  Hey,.

  Provide the following information to learn more:

  3750 side:

  #sh ip int br | ex-United Nations

  #sh int g1/0/49 trunk

  #sh int g2/0/49 trunk

  #sh vlan br

  3850 side:

  #sh ip int br | ex-United Nations

  #sh int g1/1/1 trunk

  #sh int g2/1/1 trunk

  #sh vlan br

• Can ping cRIO but unable to connect to the MAX

  I have a cRIO 9066 put in place on a local subnet. I think that all the software and drivers are correct. I have deployed my program and it works great except... When I add some optical converters of fibre in the mixture. Here is my system:

  PC--> cable ethernet--> ethernet switch-->--> cRIO ethernet cable * it works fine *.

  PC--> ethernet cable--> converter of fiber--> fiber--> ethernet switch (FPS)-->--> cRIO ethernet cable * unable to connect to MAX *.

  When I connect with ethernet cables all the way through, the ping time is<1ms ttl="" is="" 64.="" when="" i="" add="" the="" fiber="" converter,="" i="" can="" still="" ping="" the="" crio="" but="" ping="" time="" goes="" to="" ~250ms="" and="" ttl="" goes="" to="" 247.="" then="" max="" can't="" connect="" to="" the="" crio.="" is="" my="" connection="" speed="" too="" slow="" for="" max="" or="" the="" crio="" to="">

  My converter fiber and ethernet sfp module switch are all 1000 MB/full duplex. It is run only on a 10 m fiber. I tried several fiber optic cables. I tried the sfp in several locations. My sfp and the switch are both Advantech so I guess that they are compatible with each other. At this point, I plan to buy just a card PCIe fiber for my PC, but I thought I should check first with the experts.

  Thank you

  Hello

  There is a timeout OR max. The default value is 4000 Ms the reason why you are not able to detect the cRIO in NOR-MAX may be because the packages are damaged along the way. If you do not want to check this, you can always monitor the packets with WireShark with two different sets high. In this way, you can see if the packets are defined correctly or not.

  I hope this helps!

• Multi airports network problem

  I have an acting express airport as my internet gateway / firewall/router for 5 other airports that are each the clipping value. It works fine for a while but on a regular basis one or more additional airports gets 'out of sync' and needs to be reset to restore the functioning of connections wifi devices. All airports are 'green', even when not give ip addresses to wireless devices. Each airport has a static outside the DHCP range, but compatible with the network ip address. Each has identical wireless, security and bridge settings. I eventually addresses DHCP or router set in a way that is not ideal for consistent operation? See the screenshots below (1 global configuration, two are the "fiber" gateway/DHCP airport, two are from one of the additional airports):

  

  

  It is apparent from the first screenshot that all the base stations are connected to the "fiber" by Ethernet, except 'the barn stables', which seems to be connected by radio to the base station "barn." Is this correct?

  The 2nd generation AirPort Express stations base having only two Ethernet ports, you also use Ethernet switches into your current network configuration? If so, where they are placed in this global configuration?

  What is the brand and model of the Internet modem or gateway that you have the base station "fiber" connected to Ethernet?

  Finally, your needs networking requires a network of comments as well running?

• E4200 limits in Bridge Mode

  Hello

  My setup goes like this: I have a fiber to Ethernet from my ISP connector. The Ethernet cable going to one ISP has published my Zyxel router. In this router fixed phoneservice connects to give us a landline VoIP service (which is cheaper). An Ethernet cable going to the Internet port on the E4200 to the Zyxel router LAN port. That works fine but I had to put the E4200 in Bridge Mode so that it can connect to the Internet through the Zyxel router I need to use phone services my ISP provides.

  I bought the E4200 because I wanted to use the dualband functionally and get an 802.11n 5 GHz network configuration and to give me the ability to block certain Web sites and services that I know Cisco/Linksys is famous for--the ability to control your network.

  Well, imagine my surprise when I couldn't use the Parental control settings when the router is in Bridge Mode. This is the reason why I bought this router on an Apple Airport extreme. Is there anyway to allow me to use the Parental control in Bridge Mode or a better way to connect to the router with the rest of my network?

  Thanks for any help!

  If you do not have devices (mainly the game features) which require an open NAT, you can connect an ethernet cable from the Zyxel router to the Internet port on your E4200 and simply use it as a normal router without mode bridge.

  Make sure that the ip address of the E4200 is on a different subnet (just change the third octet (to the third decimal number) to something different than used as IP default Zyxel.

  You could call your ISP and ask them how to dumb down the Zyxel so that you can use the E4200 as main router and Zyxel as a modem too.

• Connecting two routers via a static route

  I have a relatively simple configuration involving a Wireless-N Router and a wireless-B router (several years).  The N wireless router is connected to the internet (via DSL modem) and accepts several DHCP clients without problem.  Wireless - b router is connected to the Wireless-N router.  To do this, I connected the WAN port on the router wireless - b to a port on the router Wireless N ethernet (did not use the uplink). I have a PC connected to the router wireless - b, so I want him to be able to hit the internet, but also be accessible to DHCP clients on the Wireless N router.  The PC connects to the internet successfully, but it does not find clients on the network supported by the Wireless-N router.  It's about my setup:

  B 192.168.55.1 wireless router (LAN) 192.168.56.102 (WAN)

  PC 192.168.55.10 (active dhcp)

  Wireless N 192.168.56.1 (LAN) x.x.x.x (internet)

  (several clients dhcp... 192.168.56.100...)

  I've added a static route in the hope that a computer on the network of the Wireless N router would be able to hit the PC, but nothing helped. I've added a static route as such, on the Wireless-N router, which was the only way that that would enable the web interface:

  Destination LAN 192.168.55.0

  Subnet mask 255.255.255.0

  Gateway 192.168.56.102

  I tried to place the router without wireless - B gateway mode, then router and changed mode, then return.  I can connect to the web interface of the router wireless - b from the PC, and I can connect to the internet from the PC.  Also, the PC is able to reach customers on Wireless N, but the reverse is not true, i.e. clients on Wireless N can't find clients on the wireless - B network. Also, I turned on the port forwarding on the router wireless - B so that it points to the PC, in the hope he would lead all traffic to the PC, but still cannot access PC.  How to configure both routers (or both set up as access point?) so that clients on the Wireless N Router can talk to customers on the wireless router - B?  For now, all customers are on DHCP, but finally, I would like to create static entries for at least two or three of them.

  Thanks in advance

  Are Linksys routers teas? If so what model is router B? It may not supported for a DHCP client port forwarding. Even if you can get the port forwarding to work for a client on router B, it will not work for several clients.

  In addition, if you have the option in router B, disable the SPI Firewall. It is the cause of the problem, in my opinion. If you do this, you should port forward.

  Is there a reason that you connect the routers via the WAN port on the router B? You could uplink using an ethernet port on the B to an ethernet port on the N and avoid all this... You can always configure router B as a point of wireless access for specific customers.

• Use of Internet reporting real-time bandwidth

  Need advice with regard to the selection of software and the physical layout. I was invited to present reports on the use of the internet;

  -IP address

  port/protocol

  -bandwidth

  We havcusco cisco 4500.

  Our ISP router's router 3400 metro (fiber to Ethernet media converter).

  We have the ISP that is connected to a port on the 4500 in vlan 99, users are in vlan (using a gateway to virtual layer 3) 44.

  If I want to make just a quick capture could I just simply connect a workstation with wireshark to a port on the 4500 and place this port in vlan 99?

  If so I guess that the same theory would work with the tool as bandwidthD which is best suited to long term capture and has a nice pretty GUI for my manager?

  Bit confused as to whether I need a mirror or span port configuration.

  Thank you

  You need to configure SPAN with VLAN 99 as a source and the port that your workstation in question is connected to the destination. Otherwise most of the traffic will never reach the workstation considered.

• VPN network E1

  Hi all

  All of the sites presented in the attached diagram are physically in different cities. I intend to have a VPN between all the sites using the Sri but on thinking local SP put E1 to Ethernet converters. It is possible and is it useful?

• VMkernel on 10G natachasery interface connectivity

  Hi all

  I've got:

  Hardware: HP ProLiant DL380 G7 + HP NC523SFP 10GbE (by QLogic), the firmware is up to date.

  Software: ESXi 6.0 U2 last available ISO custom HP.

  The server has how six physical network interface cards:

  4 * 1G Ethernet connected to vSwitch0 uplinks (management VMkernel vmk0 here, several VLANs in the trunk & port-channel, all goes well)

  Uplinks 2 * 10G Ethernet connected to vSwitch1 (these cards are for NFS and vMotion), be they vmnic4 and vmnic5

  The question that I am running comes on maps of 10 G and vSwitch1 (and Yes, I tried to remove-everything-and-recreate-it-all-from-scratch).

  The vSwitch was supposed to be used for the connection of NFS over 10G to ESXi storage using a VLAN isolated not routed.

  Vmnic4 vmnic5 and 10G uplinks are connected to a Cisco 4500-X VSS stack (ports are in trunk mode), standard MTU of 1500 everywhere, no jumbo frames don't yet.

  So, when I add a port VM group and define a VLAN ID (say 3, or the 10.10.3.0/24 subnet) for the traffic of the virtual machine - VM is accessible via vSwitch1 and Physics 10G NIC, rattling of the virtual interface of the Cisco switch very well.

  But when I add a port group VMkernel wearing the same VLAN ID and add an interface vmk1 - he reached the VM on the same virtual switch very well (which means that connectivity is OK inside a vSwitch), but could not ping/ARP/what whether through physical EPS of 10 G.

  Tried using a stack of TCP/IP by default, but also to create a new - no effect too.

  
  

  For now, I have tried all ways to diagnose and/or fix it, except perhaps for the black magic - removed the second physical NETWORK adapter on vSwitch, deleted everything and re-created vSwitch and port groups/vmkernel from scratch, without result.

  When I try to ping the vmk1 of the physical switch and vice versa ARPs are incomplete as there is no connectivity of L1, but the fact that VM pings anything on / subnet 24 fine makes me believe that the wiring is OK.

  I tried setting Cisco switch ports to switchport access mode and VLAN3 and remove the VLAN tagging on VM and VMkernel port, in the same direction - VM pings without problem and VMkernel groups does not work.

  After a week of reading, checked everything I can think of and trials, to anything not made, I would be very grateful for any ideas on that.

  Thank you very much!

  To the right: re-setup of the ESXi nihilo resolved the automagically, phew.

  Or maybe it was an update of the HP firmware somewhere along the way. Or by using only new ESXi 6.0 customer web and avoid completely the installable old...

• ESXi and equipment series

  Hello

  I would like to move some of our servers the 1.06 Server vm to esxi 3.5. All the vm is running centos 5.2.

  I have yet 2 servers to convert, because of the physics of the serial ports not supported in esx.

  The first has an analog modem on ttyS0, secondary had a GSM modem on ttyS0.

  As far as I know, it is not possible to connect a usb device to a virtual computer on esxi (or at least, I can't add a usb controller), so usb & lt;-& gt; series converters are not a viable option.

  For the modem, I thought internally. Are there compatible models, so that I should look at?

  For the GSM modem, I thought the series & lt;-& gt; ethernet converters. Is there a pro/consfor those?

  Thank you

  Giuliano

  For USB devices, we use USB to Ethernet that works really well and is much better than plug in USB devices in any server.

  I don't think its possible to get a serial through ESX device, is it USB-> Serial converter?  If you can you use it in conjunction with the USB to Ethernet

• Topology line EtherCAT with fiber/fiber converters

  Hello

  I have a request where I will order several NI 9144 slave chassis in a line of a master cRIO topology. The chassis must be 10kV + isolation from each other and the captain so I'll use converters of fiber on the link ethernet between each frame. The lengths of links are relatively short)<>

  Fiber converters does meet a particular specification, and if so do you have any recommendations?

  I'd better be using using standard Ethernet with NI 9149? I can cope without the deterministic calendar.

  Thank you

  Richard.

  Hi Richard,

  The EtherCAT protocol normally works on 100BASE-TX and can also run on 100BASE-FX (Sources here and here). I'm guessing that you have seen the KB that explains that you need for different cheating / hubs for EtherCAT and makes you wonder if the optical converters fall into this same category?

  The need for special switches / hubs is because EtherCAT junctions stars work differently that normal Ethernet as the packages hubs need a particular routing. However, optical converters online and do not affect the sense go packages. They are just bit conversion of the tensions light pulses. The main thing to consider would be how much latency converters to introduce network - as this will eventually affect your EtherCAT minimum cycle time.

  That said, NEITHER does not test the optical converters, but I've heard customers who use optical converters before (link sorry, not turned to the audience of reference available). As I mentioned above, the EtherCAT protocol specify how 100BASE-TX and 100BASE-FX, so I'll make sure the converter is in conformity with these standards.

• SG 300-10. Fiber mapping of ethernet ports (VLAN)? ...

  Hello

  the incoming fiber on ports 9 and 10 are on different subnets.  I need to map the subnet on the 9-1-9 ethernet ports and port 10 on its own.  I have the device IPv4 address a static address on the same subnet as port 9.  I don't know if there is an easier approach, but I tried to map the ports using VLANs (see attached screenshots).  We do not yet have the fiber link for port 10, so I have not had the chance to test, but I wanted to confirm that my setup is healthy.  I used the vlan by default for ports 1-9, because I need to manage through this subnet.  I added vlan 10 for 10 port, but I do not know if I have it configured correctly... Please notify.  Thank you.. !
