I am Stuck
VSS is up on two different pairs of 6509.One pair is Core & another pair is Access.
I have configured Layer 2 EtherChannel between these VSS's(VSS Pair to VSS Pair MEC). VTP information is passing through between VSS Pair to VSS Pair MEC but I am unable to pass layer 3 communication(simple ICMP). In the beginning, this Port-Channel was getting blocked at Core VSS side by STP, that is the strangest thing I have ever seen. After disabling STP on this port-channel, trunk came up & VTP started passing information successfully.
If I do a ping & debug ip packets detial I can see encapsulation failed instead of routed via FIB .
Sh ip arp : shows incomplete Mac-Address
Arp operation is failing even they are directly connected...
And I am using SUP720 Gig UTP ports for this MEC.
Performed so many known and unknown trouble shooting steps with no luck. Please clarify, if something being missed.
Your immediate response & help will be highly appreciated.
Thanks & Regards
