VLAN Bridge (fallback bridge) support on 4507R switch

[arumugasamy]

Dear Gaurav and team,

After we delivered and installed the core 4507R, found that the internal lan running main frame ibm with the PC software SNA type software to take the printout from the mainframe console.

I opened the TAC case and TAC engineer told that this switch does't not support fallback bridge feature for the non-ip traffic.Then i replaced 4507R with 3560 L3 switch and the PC communications software works fine.

Could u help me with the work around to use the 4507R switch in place of 3560 in order to support the PC comm SNA applications.

What about ethertype access-list.

Please come with solutions for this issue.

Thanks

swami
