We have a Cisco 3845 that terminates a T3 circuit from the internet provider. Currently we are contracted for 15Mbps and we are upgrading the speed to 45Mbps.
This is the current configuration of the serial interface:
ip address x.x.x.x 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp
no peer neighbor-route
dsu bandwidth 15300
So do I just need to change the "dsu bandwidth" to 45000 to upgrade the speed. The provider has already notified that they have updated their side.
