Hi,
I have alot of 5400 Access servers that has increased processing, Can anyone
make anything out of these show outputs
The AS 5400 has a FastEther interface that is connected to the uplink of a
DSLAM on both AS.
If anyone has experience here, i'd send you the configurations.
I have included the following commands on both AS:
sh run int Fast0/0 (uplink to dslam)
sh adj
sh cef drop
sh cef not
sh int fa0/0
sh proc cpu sor
sh proc mem sor
High_CPU-as01#sh run int FastEthernet0/0
