Bug in show run-config - Githubissues

claudiughioc commented 11 years ago

When running "show run-config" all the possible VLANs are displayed, except for the ones configured in the switch. This problem has been met with the "linux" back-end but must be checked for "lisa" too.

Commit 395b21dd1f6a1b09328328fe748cc5efb6eda83a fixes the CLI and the "linux" backend. The "switch" module returns garbage on get_vdb, a bitmap with random zero values. This change may have triggered other bugs in CLI so this is still unstable for the moment.

Commit bed0305abb4236bac40064df84960412041c67df[1] in lisa-kernel solves the problem in the "switch.ko" module. I remember that I discusses with Radu R about how the VLAN bitmap are supposed to be created in the back-end:

zero for allowed VLAN
one for forbidden VLAN, hence the appropriate macros in net_switch.h: sw_allow_vlan resets the bit corresponding to the given VLAN and sw_forbid_vlan sets the bit to 1. I tested the latest changes with both original and "bridge + 8021q" implementations and it works for me. If anyone else tried this, it would be perfect.
