I have some problem with Cat 3560 running c3560-ipbase-mz.122-35.SE1. When we configure voice vlan on the access port, and the access port is connected to PCs, we encounter packet 50% drop. The reason we configure voice vlan at this stage is to facilitate IPT deployment for next month.
Once i remove the voice vlan command, everything is back to normal.
Has anyone encounter this problem before? I search the release notes and couldn't find anything on it.
