NOS, VDX-6740 - mgmt interface unable to ping back.

[Pawel_Eljasz]

hi everyone,

I might have somewhat not straightforward setup:

VDX's mgmt iface is hooked into a non-extreme switch, whose ports are in access more, not-tagged.
Then, nodes/clients ifaces are vlans and are hooked into the same switches, on ports which are in General mode and tag the vlan from nodes/client.

Now, nodes/clients can ping VDX's mgmt iface, can ssh but, VDX does not ping back, fails as unreachable.

I swear it was working, I think, but I've been fiddling with switch recently and I can only presume changed something I must have.

But what...
What can be the problem & the fix here?
Many thanks, P.

A normal ping (ex. VDX# ping X.X.X.X) will use the default-vrf by default. The "show vrf" command will show all the vrfs:

Ex.
VDX# show vrf
Total number of VRFs configured: 2
VrfName VrfId V4-Ucast V6-Ucast
default-vrf 1 Enabled Enabled
mgmt-vrf 0 Enabled Enabled

ps. Where from can I get all my VRFs?
I presume that any other ping will not work if not supply VRF as an argument, right?

many thanks, P.

If you are not doing so already, please specify the management vrf when doing the ping test and report the results:

Ex.
VDX# ping X.X.X.X vrf mgmt-vrf
