Uplink port VLAN

• Ports & VLANS

  Hey all - serious brain issue today.

  I have a core switch with a port set to VLAN 10 & 20 tag traffic.

  In this core switch port, I have a GS748T, where I'm the odd ports # be vlan 20 & ports even # to vlan 10.

  Objective:
  I have a DHCP server, which serves the two VLAN - so I was hoping that plug into one line, withdrew a DHCP server IP address, but not luck.

  I've been playing with the PVID & VLAN settings on the ports, but impossible to find the right combo. What is the setting for the port of uplink on 748?

  Thoughts? Help?

  Thank you!

  -Tom

  I have it.

  GS748:
  

  DHCP release/renew unsuccessful for different networks when I move the cable to different VIRTUAL local area network ports.

  So:
  Interface/Port 1: VLAN 20.
  VLAN 20 membership: U
  Port PVID config: VLAN 20
  Uplink port: VLAN 20: T

  Interface/Port 2: VLAN 10
  VLAN 10 members: U
  Port PVID config: VLAN 10
  Uplink port: VLAN 10: T

• Broadcast/multicast designated uplink port

  Hi all

  If I have a chassis with two modules 2208IO and FI6248XPs,

  I'm pinning each server, on each uplink.

  I place an uplink designated B/m on the port of FI6248 1, this means only the Server Blade 1 can receive traffic B/M?

  As far as I know, if I want to access a server I need to know what is the ARP and MAC address is a broadcast traffic.

  So how the remote does find out local server MAC address, like Blade 2,3,4... ?

  Thank you

  Hello

  UCSM 1.4 and earlier, we had NOT the possibility to implement a leaking layer 2, so he used to work the way you're so the recommendation then was to swtich to end host (EHM) to mode switching Mode, however, now with 2.0 and 2.1, we can implement disjoint Layer 2.

  {Now is NOT recommended to use the switch mode, EHM in new versions has all the features you need to not lose the features available here}

  It's the way it works from 2.0 and newer:

  

  In this way, you can have an uplink by VLAN designated as receiver for B/M.

  Check this, it may help you understand how it works and how to get around the traffic:

• Half of the blades fell when creating a new channel of uplink port?

  I have a pair of 6248UP fiber interconnection (A and B) with blade servers connected. The switch upstream is Nexus7k. Fabric A and B each right has now a channel of uplink port to the Nexus switch upstream. I add a new Nexus switch to connect to the interconnection of fiber. The plan is to have uplink some VIRTUAL networks for Nexus one pass and uplink some VIRTUAL to the second Nexus switch networks.

  After that I configured the new Nexus switch with a channel port (only allowing some VIRTUAL networks) and corresponding port created on fabric channel A and B, new ports-channels have increased. However, half of the blade servers were down after that. What could be the reasons for this problem? Is it because half of the blades have been pinned dynamically on the new channel port, but the new port-channel side Nexus allow only some VIRTUAL networks?

  Is there a way to configure the Channel ports on fiber to interconnect with only the trunk through some VIRTUAL networks? for traffic from the server would not be sent to the port-channel where VLAN server is not allowed?

  Thank you

  In general, all NICs for/vhba of a fabric are declining, if all uplinks of this fabric are declining.

  It's not clear to me, what you're trying to achieve?

  If you create a global VLAN (for the two fabrics), this vlan is automatically inserted in all dependent North trunk links, unless you configure a leaking installation

  (http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns944/white_paper_c11-692008.html)

  Create a new vlan on UCS requires of course also this vlan is created on the switch connection and vpc by default allows all the VLANS. Could it be, that the vlan not appeared on the switch and was therefore not upward on the trunk?

• Connection EQL 6110 X (10G SFP +) PowerConnect 6224 10 Uplink ports

  Dear friends,

  Need your help...

  Please let me know if I can connect EQL 6110 X (10 G SFP +) storage to ports 10 G SFP + PC 6224 for iSCSI to my servers on a local network connectivity that is 1 G.

  Correct, do not use the uplink ports for Gigabit Ethernet switch for 10GbE tables.    It can connect, but performance and stability will most likely suffer.   So has been the experience of other customers who have tried to do.

• Limit the number of Port VLAN UCS

  Hi, Cisco:

  Is it possible to INCREASE the limit of the number of Port VLAN of 6000 by FInterconnect 1.4(2b) running?

  Imagine I have 4 and selected VLAN 10 vNIC by Profile Service and 2 vHBA.

  So in this case, how many local network VIRTUAL ports will be used? It's 60 or 40? Assuming that it is 60, he the man I CAN ONLY HAVE 100 Service profiles?

  I was wondering WHY is the VLAN Port count limit so low? What about the other fabric and HOW it contributes to the limit of the number of Port VLAN?

  Please notify.

  Really appreciate it as we roll and unroll UCS mass.

  Yes makes sense.  The golden rule in access to resources is only allow what you need, not just what is available.

  See you soon,.

• Uplink Ports Fibre Channel - UCS GUI Configuration Guide

  Hi all

  Could someone please explain which means that what follows in the Configuration of GUI of UCS guide @.

  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.

• The question of the Uplink port speed

• stop the ethernet uplink port will cause the port of the unit down

  Dear all,

  I want to make sure that this kind of network traffic will communicate internal fi.

  I've disabled the uplink port and found the path of material has also declined.

  Port of the device must road toward uplink port and then back to UCS server?

  Thank you for the clarification.

  Best regards

  Dennis Dai

  Expected behavior.  By default, if there is no uplinks online & fwd, then all links South (Server binds and the ports of the device) will be used also to the bottom.

  See the explanation of Abi here for more information how to change this behavior.

  https://supportforums.Cisco.com/thread/2187144?TSTART=0

  In short, we must change policy control of the network of the way of the material in the Hardware tab.

  Kind regards

• 4 FC by FI uplink ports. But what a single port to send the addresses of WWPN vHBA?

  I have four portis configures as uplink FC by FI and FI woking in end host mode.

  I have 24 blades using two vHBA. vHBA0 and vHBA1.

  24 address WWPN are saved on the uplink of SAN of only 1 FC uplink.

  Same case in the other Brocade.

  That is something we don't want.

  All FC uplink ports must be used.

  We have borcade. Advised not to use the port channel.

  I can manually create groups of pin code and balance the load. But do create a lot of model vHBA and tedious work.

  Other autour work?

  Help, please.

  (1) you can only use Port FC channels connecting to Cisco MDS and Nexus or for FC traffic.

  (2) on each FI, run the following command:

  (nxos) # see the npv flogi-table

  You should see the WWPN by connecting to the FIs, or you have problems downstream with your configs vHBA.

  Make sure that vHBA0 is mapped to FI - A and vHBA1 is mapped to FI - B and the proper vSAN is assigned to the vHBAs. Also ensure that the FC connections are not crossed the FIS for the brocades.

  model vHBA allows very simple, consistent deployments.

• VSAN membership down on the CF mapped uplink port

  Hello

  Since I upgrade Cisco UCS Manager, all frame and fabric of interconnections of version 2.2 (1), I have a few minor flaws.

  I configure ports 31 and 32 as FC uplink ports and mapped each port to a vsan:

  Port 31 = VSAN 'blue '.

  32 port = "red" VSAN

  (I know, it is not common to map two different VSAN to the same fabric, but I have to)

  Since the update, I get minor flaws:

  31--> FCoE or FC uplink port is broken on 'red' VSAN / membership-down

  32--> FCoE or FC uplink port is broken on 'blue' VSAN / membership-down

  I have no channels of port FC or FC enabled link mode. Interconnection of fabric is EHM.

  Even in other tissues.

  Can anyone help me or is it the same cosmetic problem as stated in the quote?

  FCoE Uplink vsan membership fault for any vsan not configured upstream Symptom:
  
  Fabric Vsan Membership Down fault message on FCoE uplink ports
  Severity: Major

  Hello Danny,

  Yes, it is a cosmetic issue in UCSM 2.2.1

  the question is followed by

  https://Tools.Cisco.com/bugsearch/bug/ CSCum89468

  The one that you cited ( CSCud81857 ) is specific to the rising FI FCoE in version 2.1 of UCSM.

• Group of VDS uplink port setting

  Hi all

  I'm new to VDS.

  I found that I can not change setting of group VDS uplink port image attached and many VDS menu editting is not editable.

  I wonder why I can't edit VDS setting. Kindly pls advise.

  This is because there is no need to put anything on the uplink.

  Uplink port groups are distinctly different from normal port groups. There is absolutely no reason to have these settings on the uplink port groups, because they generate all the executives themselves and traffic simply forwards to the vNIC/vmk interfaces on port groups attached, there is no need to expose a Visual similarity like this again. These parameters and others like safety apply to groups of normal port only.

• Config port / VLAN on switch MXL

  I'm not a network engineer, but I try to set a port to my MXL switch to a VLAN that will route traffic on virtual machines on a local network of calculation.

  This is the port Te 0/52 on the back of the MXL and I am running ESXi on servers in my m1000e.  In fact, I have two MXLs in the tissue A of the m1000e configured with VLT via the interfaces of the FourtyGig.  This part has been implemented by people of Dell Tech Services, making the installation.

  Here's what looked like the config to start:

  dsa1 #show vlan

  Codes: *-Default VLAN - VLAN, GVRP, R - G remote control Port Mirroring VLAN, P - primary, C - community, I - isolated
  O Openflow
  Q: U - no identified, the T - tag
  x - unidentified Dot1x, X - Dot1x tag
  o - unidentified OpenFlow, O - OpenFlow tag
  G - GVRP tag, M - Vlan-stack, H - VSN tagged
  i unidentified intern, I - labeled internal, untagged, V v - VLT - VLT tag

  Ports Status Description Q NUM
  * 1 U active Po33 (0/33.37 Fo)
  U Po41 (Te 0/41-44)
  Te U 0/1-32
  115 active Mgmt T Po41(Te 0/41-44)
  V Po33 (0/33.37 Fo)
  Te T 0/1-32
  486 active VMGuest T Po41(Te 0/41-44)
  V Po33 (0/33.37 Fo)
  Te T 0/1-32
  Te U 0/49-50

  And I wanted to add VLAN 1000 to calculate, so I did the following:

  dsa1 #conf

  dsa1 (conf) #interface Te 0/52
  dsa1 (conf-if-you-0/52) #show config
  !
  interface TenGigabitEthernet 0/52
  no ip address
  MTU 12000
  hybrid portmode
  switchport
  FlowControl rx tx off
  spanning tree rstp edge port bpduguard stop-on-violation
  no downtime

  dsa1 vlan (conf) #interface 1000
  dsa1 (conf-if-vl-1000) #show config
  !
  interface Vlan 1000
  Description information
  name computer
  no ip address
  Tagged TenGigabitEthernet 0/1-32
  Unmarked TenGigabitEthernet 0/52
  no downtime

  VLAN now looks like:

  dsa1 #show vlan

  Codes: *-Default VLAN - VLAN, GVRP, R - G remote control Port Mirroring VLAN, P - primary, C - community, I - isolated
  O Openflow
  Q: U - no identified, the T - tag
  x - unidentified Dot1x, X - Dot1x tag
  o - unidentified OpenFlow, O - OpenFlow tag
  G - GVRP tag, M - Vlan-stack, H - VSN tagged
  i unidentified intern, I - labeled internal, untagged, V v - VLT - VLT tag

  Ports Status Description Q NUM
  * 1 U active Po33 (0/33.37 Fo)
  U Po41 (Te 0/41-44)
  Te U 0/1-32
  115 active Mgmt T Po41(Te 0/41-44)
  V Po33 (0/33.37 Fo)
  Te T 0/1-32
  486 active VMGuest T Po41(Te 0/41-44)
  V Po33 (0/33.37 Fo)
  Te T 0/1-32
  Te U 0/49-50
  1000 active Compute T Te 0/1-32
  Te U 0/52

  But I wanted to add THAT VLT Po33 tag to the new VLAN because there is in others, not because I really understand what it does.  In my view, it is used for load balancing?  If I label it with the command 'tag Po33' in the config of vlan, out with the status "T" instead of "V".

  Here are the details of the VLT:

  dsa1 #show vlt detail
  Local LAG Id counterpart LAG Id status Local Peer status Active VLAN
  ------------  -----------  ------------  -----------  -------------
  41 41 UP UP 1, 115, 486
  dsa1 #show brief vlt
  VLT area in brief
  ------------------
  Domain ID: 100
  Role: secondary
  Primary role: 4096
  ICL Link Status: to the top
  Status of heart rate: upward
  VLT Peer status: to the top
  The local unit ID: 0
  Version: 6 (4)
  Local system MAC address: f8:b1:56:09:70:b1
  MAC address of the remote system: f8:b1:56:09:70:fd
  Configured the system MAC address: 00:01:00:01:00:01
  Version of the remote system: 6 (4)
  Restore delay timer: 90 seconds
  Delay-restore Abort threshold: 60 seconds
  Routing peer: disabled
  By the peer-routing-Timeout timer: 0 seconds
  Multicast peer-routing timeout: 150 seconds

  So my questions are, I'm on the right track?  It will do what I want it to do is send traffic on port 0/52 Te which is labeled in ESXi with 1000 VLAN?  Should I worry the VLT marking stuff and if yes, how should I do the VLT marking rather than normal marking?

  The connection only 1 port of MXL 1 to a device, this device is considered a switch/host an orphan. A VLT connection will have 1 port each MXL placed in a port channel and connected to a device.

  Here is a good article that covers the VLT in use with different Topologies.

  And the User Guide is a good source to have as well.

• 5524 - jumbo Frames - entire unit or only to certain ports / vlan

  Hello

  is - anyone idea, if possible to use frames only for ports specific it s?

  After enable JumboFrames, it will create a problem of common computers network traffic? I intended to create a VIRTUAL LAN to connect to the storage and r.620 (under XenServers).

  * We plan to use this unit to connect a Dell Power Vault MD3200i volumes as iSCSI offering.

  * According to our (ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powerconnect/powerconnect-5524_User%27s%20Guide_en-us.pdf ) switch mannual: "Activation iSCSI automatically enables Jumbo frames and allows the control of flow on all interfaces.

  Allowing the frames on the switch will allow the frames extended on all interfaces. I don't see a way on this option to activate the frames extended on a specific interface or VLAN. Allowing the Jumbo will not create any problem with common computer network traffic. If this switch is connected to another switch, it's a good idea to have some Jumbo frames enabled on the interface of switches connection also.

  Hello

  You can use them for what you want.  They can connect to the virtual machines, stand-alone server, workstation, inter-switch etc... They can also be access or trunk ports.
