I am facing a strange problem with 4507R+E VSS pair. The supervisor engine is 8E in the switches. The issue is that when I connect a host directly to the standby chassis I am not able to reach internet. The same host when connected to the active chassis does not have any issue. The ios version is cat4500es8-universal.SPA.03.07.02.E.152-3.E2.bin. Please help me to resolve this issue
