• Connection of fabric interconnect with the Cisco MDS switch

  I'm new to the unified fabric and try to understand it.

  There are clients who connect fabric connects directly to switch MDS without any Nexus 5 K between the two.  If the fabric of interconnections are able to provide connectivity to the LAN and SAN Islands then why you install Nexus 5 K between two switches to add an extra jump.

  Thank you

  Hello

  Most of the clients do the following:

  -connect FI upstream for example N5k with vPC for Ethernet (IP)

  -connect FI upstream for example MDS for the classic FC

  This implies that between the blade into the chassis and FI you run FCoE, integrating CF and Ethernet on the same means of transport; then, on the FI, FC and Ethernet is disintegrated.

  The other choice would be Multihop FCoE, linking FCoE also FI and N5k and make the disagregation it.

  However, if your storage subsystem is FC and FCoE, I wouldn't recommend Multihop FCoE (I see only a minority of clients to do).

• How do I save a tech 'show' and a 'running config"of MDS switches

  Hi, guys

  I am a newbie of DMS switches.

  but I had a request this week asking me to actively save a tech 'show' and a 'running config"MDS switch...

  so my questions are:

  (1) if I want to save the configurations of MDS, including commnds should I launch? or simply 'see the tech' enough?

  (2) is that the MDS itself have the Save function? for example, you can ftp configuration somewhere?

  Please help point me in the right direction or y at - it of the official referece docs that I can refer?

  Thanks in advance!

  (1) the configuration of MDS backup that you want to run this command:

  copy running-config

  and then, you have several options where you can send in for example you could tftp it

  copy the running-config tftp://yourftpserver/mdsbackup.txt

  (2) I don't think there is a native solution that performs scheduled backups, but that is easy to write a small bash/perl script.

• How to distinguish the physical interface and logic (subinterface) interface to the Cisco router/Switch?

  Hi Expert,

  How to distinguish the physical interface and logic (subinterface) interface to the Cisco router/Switch? Can you please clarify a formal way for this so have?

  A physical interface is numbered with the same name of the interface when printing on the physical port. For example "GigabitEthernet 0/1" corresponds to port 1 of the 0 module (or the base unit).

  A logical interface can be a subinterface on a routed port and will have a point ("". "") preceding the number sous-interface (ex. GigabitEthernet 0/1.1). It can also be a loop or a virtual interface (on a router this could also include interfaces like the tunnel and virtual tunnel or VTI types). A switch may also have a VLAN logical interfaces (e.g. interface vlan 1) which are used as layer 3 virtual interfaces of type.

• Cisco Catalyst 4503-> Cisco 3560 L3-> Cisco 2960 L2-> Cisco SMB switch

  Hi Experts,

  I am trying to add a Cisco SMB SF300 - 24 Switch to an infrastructure that has only the Cisco Catalyst switches

  The base layer is Cisco Cataylst 4503. Distribution is Cisco Catalyst 3560 and Cisco 2960 switches access layer.

  There are about 30 VLAN present in the infrastructure that is announced to all switches using VTP. Inter VLAN routing takes place at basic switches

  by creating the Interface VLAN for each VLAN of L2.

  1. the new 150 VLAN must be created on the new Cisco SMB switch. If I create a corresponding interface 150 VLAN on core switches, it will forward the other VLANs traffic just as he is currently working for Cisco 2960 Catayst switches?

  2. While they inspected, I could see that the DERIVATIVE is not supported on the Cisco SMB switches and I would need to go GVRP if I need to make advertising information to other switches VLAN. But since GVRP is only supported on CatOS and there is no inter operability between GVRP and DERIVED, I would need to manually create the VLAN on the new switch. Is this correct?

  Help, please!

  Thank you very much

  Good afternoon Anup Sasikumar

  Please use our forum

  My name is Johnnatan I am part of the community of support to small businesses, I saw your post and I understand that you want to configure VTP and GVRP.

  I'm afraid you will have to configure it manually each Vlan in each device CatOS GVRP, in order to keep their databases vlan in sync. As you say, VTP is support it not in CatOS

  You can try to connect the two protocols, but I encourage you do not follow this procedure.

  On your question about intervlan routing, if you create a corresponding interface 150 VLANS on switches to base it is routed, if your configuration is correct (port access, ports of junction, intervlan etc..)

  I hope that you will find this answer useful, if it was satisfactory to you, please indicate the question as answer.

  Please evaluate the useful messages.

• Connect a Cisco L3 switch behind a 871 using easyvpn

  Hello

  It is our habit to use easyvpn on 871 routers to connect our remote to our ASA 5500 VPN concentrators.

  It works well, we define them VLAN on the 871 and connect Cisco L2 switches behind the VPN routers.

  Problem is that now we have to connect the Cisco L3 switch behind the VPN routers and if we face problems of routing...

  No way to make works for all the VLAN defined on the switch of L3!

  I guess we have to use a specific configuration (IRB?).

  Or do we have to use IPSEC-L2L instead of the easyvpn?

  Thanks for your help.

  Kind regards

• Cisco Nexus switches

  I'm looking to deploy a series 5100 Cisco NEXUS switch at 10 Gbps.

  I know that the Nexus is supposed to work with the converged network adapter (for 10 Gbps FCoE, etc.), but can it operate without an ANC?

  I want to put some passthrough 10 Gbps modules in my Dell m1000 chassis and the cables directly to the Nexus switch.

  I know that the Nexus is perhaps overstated for this solution, but it is a step in the UCS solution for us.

  Thoughts?

  James

  Hi, you don't need special drivers for "low latency" 10 Gbit ethernet on a 5 k.

  for example, to switch non-nexus 5 k

  PING 10.10.10.1 (10.10.10.1) 56 (84) bytes of data.

  64 bytes of 10.10.10.1: icmp_seq = 1 ttl = 255 time = 0,530 ms

  64 bytes of 10.10.10.1: icmp_seq = 2 ttl = 255 time = 0.618 ms

  and a nexus 5000 with a qlogic 8152

  PING 172.16.78.3 (172.16.78.3) 56 (84) bytes of data.

  64 bytes from 172.16.78.3: icmp_seq = 1 ttl = 128 time = 0.150 ms

  64 bytes from 172.16.78.3: icmp_seq = 2 ttl = 128 time = 0,134 ms

• MS NLB Multicast configuration on Cisco Bladecenter switches mode

  We seek to MS NLB Multicast configuration on Cisco Bladecenter switches mode. We are adding static ARP and CAM entries for each port on the switches kernel that

  the Bladecenters are connected to, or just the port of the virtual machine arrives at

  push traffic at this time here? If we add it to a single port,

  How vmotion will work... because it seems that we have to manually

  transfer the arp from one port to the other entry.

  We add the static ARP entry to the entire Cisco switch. If you can VMotion VMs NLB to another host that is physically connected to another switch, then this switch have thus added ARP entry. We have not tested the configuration only on the specified ports. But if you do, make sure that you include all the ports connected to the physical switch (if for DS you have four natachasery configured in a vSwitch...).

  Here's a guide to how we have configured it several times in our society.

• WAP321 Cisco PoE switch

  Could someone tell me please to a small businesses of Cisco switch that would be capable of powering of five WAP321?

  I do not know the power on these access points profile but have noticed that the PoE injectors pump 16.8 watts MAX. I find anywhere what the power profile is on WAP321 APs but ~ 17 WATTS seems to be quite high.

  In fact, I was interested in the SF100D - 16 p which has a budget of power of 64W on 8 ports... the price range is within my budget.

  If someone could tell my, if the SF100D - 16 p can power 5-6 WAP321 enough? Thank you.

  Hello Rob, the answer is Yes, the SG100D - 16 p will manage enough 5 AP.

• How to configure the VLAN for Cisco SG500 - switch 28

  Hello

  First of all, it's my first post here, I hope that someone can help me and please be patient because I am very little known.

  OK, so let me explain to you the scénarion I face and I hope someone can help me.

  We have a Cisco SG500 - 28 port gigabit switch in our workplace.

  Our goal is to create 3 VLANs and separate networks between the various departments.

  Vlan1 (which is the default VLAN in the switch)-will be used for the COMPUTER service and management.

  VLAN100 - will be used for business.

  VLAN200 - will be used for clients who need to connect to internet via WiFi.

  I created VLAN100 and VLAN200, and VLAN1 is there by default.

  I want to use port 13 for VLAN200 and to connect the-Wifi access point there.

  The uplink is in port 25.

  I would be happy if you could explain things first to a more general, abstract level, and then we can look at the specific scenario that we have.

  SG500 Cisco - 28 Gets a Sophos UTM 9 router internet.

  I need to take care of the inter - VLAN routing so, subnet and DHCP

  Thanks in advance,

  Sincere greetings,

  D

  Hi Desmond, looking at this DHCP pool it looks correct.

  For the second part, you waant VLAN 200 only work on VLAN 200, that's fine. So if you have an access point, and everything on the VLAN 200 connects to the access point, you can make an access to this list. The access list is entered only, which means the inbound interface.

  So if you have a gateway connecting to #1 port. You'll need to build the access list and apply it to port number 1. That's assuming you make a list of access 'decline' subnet source IP of VLAN 200 destined for the other subnet, that you do not want access.

  The image on another post to fill out your reference numbers, then for the ACL link, it should be placed on the interface VLAN 200 first comes to the switch (IE, the port the access point connects, make sure that you choose to bind by port instead of per VLAN)

• A SG300 Cisco SMB Switch will support DHCP Option 156?

  Hi all

  Is it possible to configure the 156 on a Sx300 Cisco DHCP scope option? Its for Shoretel IPT... I noticed that the option is not available through the user interface. But I tried the other day on a switch with the latest firmware via the CLI and it almost worked but I couldn't switch to accept the exact string that I needed... For example below (the Cisco classic):

  the option ascii 156 'ftpservers = 172.16.250.21, country = 7, language = 4, layer2tagging = 1, vlanid = 100 '.

  Guidance gratefully received...

  Thanks in advance

  Matt

  Hi Matthew, the options supported on the DHCP server are as follows:

  1,3,4,6, 12, 15, 44, 46, 50, 51, 53. 54, 55, 56, 58, 59 and 61.

• HSRP support on the cisco SMB switches

  Hello!

  Just a question.

  One of the Cisco Small Business L3 switches support the failover as HSRP, VRRP, and GLBP entry protocols?

  Thanks in advance

  Hi Dejan,

  Oops, I overlooked the fact that you need L3 switches.

  In this case, indeed the Catalyst 3560 would be the best choice.

  Thank you for your trust to Cisco!

• Cisco SG300 Switch - 28 p

  We have four switches Cisco SG300 - 28 p and a Linksys SRW2024 switch in a closet. I've been here for awhile and I'm finally getting the time to straighten out the mess of wires in this cabinet. I know that you have to connect the switches and at that time, they use one to 28 ports. Can I use the gigabit ports instead? Thanks for any help.

  No worries, glad it helped... Yes, the numbering of the latest ports bit is a bit strange
