Nexus 5000 switch-profile sync via SVI?

[Ralf Kleineisel]

Hi,

is it possible to use a Vlan interface (SVI) for syncing the switch profile on two 5596?

I tried this:

2 x 5596UP with NX-OS 5.2(1)N1(3)

Connected with 2 x Twinax on ports Eth1/15 and /16, portchannel 3.

The Po3 is a trunk, allowed Vlan is 439. Both 5596 have a SVI in Vlan439 with an IP. I can ping between the two 5596.

# ping 10.9.8.4
PING 10.9.8.4 (10.9.8.4): 56 data bytes
64 bytes from 10.9.8.4: icmp_seq=0 ttl=254 time=0.887 ms

When I try to to this:

switch-profile k

  sync-peers destination 10.9.8.4

I get:

# sh switch-profile status

switch-profile  : k

As soon as I change the sync-peers destinations to use the IPs on the mgmt0 interface everything works fine:

# sh switch-profile status

switch-profile  : k

Yeah I've always used the IP of the peer keepalive link. I think it might have something to do with CFS only working on ethernet and not SVIs.

Guys,

Any L3 adjacency is not supported by peer-link.

No, if you want a short answer.

Or...

Switch-Profiles feature will only work using mgmt0 interface. Here's the quote from

Cisco Nexus 5500 Series NX-OS System Management Configuration Guide, Release 6.x

Guidelines and Limitations for Switch Profiles

Consider the following guidelines and limitations when configuring switch profiles:

• You can only enable configuration synchronization using the mgmt0 interface.
