My 3660 (running 12.2(8)T5) is not bringing up more than 924 VCCs for some reason. The interface says 1023 maximum:
1023 maximum active VCs, 924 current VCCs
Any VCC I create further than that shows an end-to-end connection on the router and the far end, but the VCC status shows "INACTIVE."
Has anyone witnessed this behavior or am I missing something?
