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 _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
