I have a couple of questions concerning ERSPAN on Nexus 5500.
Can I perform ERSPAN from a Nexus 5500 without the L3 module? I tried using the management VRF as erspan-source, but it would not allow me. And I am not having much luck setting up a s...
Nexus 7700 version 6.2.
Can someone confirm whether this is possible? - I have OTV between two data centres, and I would like to see some statistics concerning which pairs of IP addresses are using the OTV. The objective is to try and put the pairs ...
I have a situation where I have an OSFP adjacency between two SVIs on different switches, through multiple L2 hops of the VLAN. (Don't ask why!) If one of those hops goes down, it will take an unacceptably long time (the OSPF dead time) before the S...

Hi,

Only once you have tracked down th...
Could you do a show spanning-tree vlan 178 on each one please? Also, it mght be useful to know the interface configurations of the trunk between the two.
"Its weird to notice that the security appliance is receiving the packets but not seeing any data capture."
I remember seeing somethig like this once. It turned out the traffic I was trying to capture was dot1q tagged, and the NIC of my capture devi...
