Hi All
I have 7606 with ES20+ module
I have two active connections on this module , one is layer 3 (point to point)
link and the other one is the link of concern
I have configured this link as a trunk with only Vlan 1700 is allowed , and SVI
is configured for that Vlan
interface G4/19
switchport
switchport mode trunk
switchport trunk allowed vlan 1700
speed nonegotiate
interface vlan 1700
ip address x.x.x.x x.x.x.x
What am facing now when I check the show spanning-tree blocked-ports I can see
that port is blocked for Vlan 1700
When I issue the show spanning-tree interface g4/19 details , I can see the
counter for both sent and received increases equally (which explains the
self-looped)
When I change to switchport mode access , I can see the port is Up and the SVI
is UP
What could be the issue and how can I solve it from my side?
Thanks in advance
BR,
Mohammad
