Hello,
This is my first stab at VPCs. Here is what we are working with for hardware:
2 5548s
2 2232s
Twinax for 5k to 5k VPC
FET-10g fro 2k to 5k VPC
HP Servers with dual port CNAs
And here is a drawing of the topology:
The 5k to 5k VPC looks good:
bottomSW# sh vpc br
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status: success
Per-vlan consistency status : success
Type-2 consistency status : success
vPC role : secondary
Number of vPCs configured : 1
Peer Gateway : Disabled
Dual-active excluded VLANs : -
Graceful Consistency Check : Enabled
vPC Peer-link status
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
1 Po1 up 1,101
vPC status
----------------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
------ ----------- ------ ----------- -------------------------- -----------
10 Po10 down* failed Consistency Check Not -
Performed
But as you can see VPC 10 which is the 2k to 5k VPC is down.
When I do a show interface ethernet 100/1/1
I get this:
Ethernet100/1/1 is down (SFP not inserted)
Which is pretty interesting since I can mange the 2k from the 5k. Here is the whole config for one 5k:
bottomSW# sh run
