this can cause an increase of cpu usage, original packets can be of normal size but then there is the GTP overhead and this leads to the need of fragmentation
My is only a guess that GTP can cause high cpu usage based on the fact that packets needs to be inspected deeply to be placed in the correct session within the GTP tunnel it is wise to open a TAC SR if this is impacting or it is going to impact service
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...

Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the

IntroductionOSPF, being a link-state protocol, allows for every router
in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
