We are buying new Cisco 2821 routers for our MPLS implementation. The routers will be used only for routing between the MPLS cloud. I'm trying to determine which WIC cards I should use at each location.
You will need 2 wic-1dsu cards to run 3m where the vwic-2mft-t1 can run 2 on one card. With 2 cards you have some failure protection but it tends to be more expensive to buy 2 cards. The vwic card can also run fractional t1 which I don't think the 1dsu can
The difference between the vwic2 and vwic card is from the obvious that one can do both e1 and t1 and the other can only do t1. The more important part is that the vwic2 has 2 clocks. This may or may not be a issue but I have sites with vwic-2mft cards with 2 t1's that I have to set the clocking on 1 to line and the other to internal to stop clock slips on one of the lines. So far I have been lucky and been able to resolve my clocking issues with this method but I am worried I may someday get a site that the lines have different enough clocks that this trick won't fix it.
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
