Hi Mike, I would recommend upgrading to 15.2(4)S3 which has been recently posted on CCO.

We use one of the VLANs as a connection directly between two routers running OSPF. This worked for over a year with no special config outside what was listed in the online configuration guide. Early last week, however, the OSPF session dropped and wouldn't come back up. After some research, it appears this is probably related to one of the several known issues in the release guides (CSCtt03126) for multicast through EFP's. Here are the relevant parts of the config (I think): no ip igmp snooping vlan 47 vlan 47 name OSPF-BETWEEN-SITES ! Start Default small port buffer fix class-map match-all COS_ZERO match cos 0 policy-map QUEUEFIX class COS_ZERO bandwidth 100 queue-limit 3932 us class class-default queue-limit 3932 us ! End small port buffer fix interface GigabitEthernet0/1 description Metro Ethernet Handoff port-type nni switchport trunk allowed vlan none switchport mode trunk spanning-tree portfast trunk service instance 47 ethernet encapsulation dot1q 47 rewrite ingress tag pop 1 symmetric service-policy output QUEUEFIX bridge-domain 47 I've got a temporary workaround in place (GRE tunnel to turn the multicast into unicast directly between routers), but would like to get back to a "normal" config. My questions are: 1. Would upgrading to the latest IOS for the switch likely resolve this issue without further config modification? Any config issues likely to be seen by going to that version? 2. I see in the release notes that there are a few likely workarounds (again CSCtt03126) - Would MST (one of the suggested workarounds) on the 3600X play nicely with a directly connected C3750X in rapid-pvst mode? 3. What is the going recomendation for stable/fewest bugs/etc on the IOS version? Latest and greatest? Thanks in advance for any suggestions. -Mike _______________________________________________ cisco-nsp mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
