65k VSS Etherchannel mac address issue?.

[jackyjoy123]

Hello,

when we remove one link out of six from the ether-channel, devices from a special VLAN are not able to communicate anymore.

 

CORE-----6 Links Po110-----6Link Po24----DISTR------ACCESS---CLIENT

 

When we add the link again it resume immediately!

I guess Port-challnel, STP etc. is working fine. Because only some clients of that VLAN has the problem. All other ACCESS switches on that DISTR. seems to working fine... krogerfeedback talktosonic talktowendys I assume a problem/Bug with the VSS. Any idea????

We plan to replace the Core with a new version 45k and thats why we need the links due to no more free between both..

 

When the link is down...I see the Whataburger survey MAC of one client on the COREs mac-table and the other not...when we resume the connection I see both. On the DISTR. I see both MACs all the time..

I assume an issue with the MAC table "Process" on the standby Switch of the VSS ...but how can I solve the ;)..

65K VSS version:Version 12.2(33)SXH2a (very old) Any known issues Idon't find by now.

 

 

Core Loadbalancing But I guess that is no issue and fine configured..

CORE#sh etherc load-balance
EtherChannel Load-Balancing Configuration:
        src-dst-ip enhanced
        mpls label-ip

EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source XOR Destination MAC address
  IPv4: Source XOR Destination IP address
  IPv6: Source XOR Destination IP address
  MPLS: Label or IP

 

DISTR: Loadbalancing

DISTR:>sh etherc load-balance
EtherChannel Load-Balancing Configuration:
        src-mac

EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source MAC address
  IPv4: Source MAC address
  IPv6: Source MAC address

thanks

The Code is too OLD honestly i remmember used in more than 7 years back i guess, you need to get in to latesdt 15.X  again depends on Sup card

is there any reason you have below config ? can you make both same and test it ?

CORE#sh etherc load-balance
EtherChannel Load-Balancing Configuration:
        src-dst-ip enhanced
       

DISTR: Loadbalancing

DISTR:>sh etherc load-balance
EtherChannel Load-Balancing Configuration:
        src-mac
