I have 4mbps MPLS line configured between two sites, currently using 3xT1 lines bundled together as 4.5mbps total. We are planning to upgrade to EOC with 10mbps line shortly. Using same router cisco2821 in both ends. Only change is to adding Fast Ethernet Layer 3 HWIC in both routers.
COS need to be reconfigured after upgrading the line ? if yes, Is there any way can find the current COS profile configuration from the existing router?.
