The operation of tx-ring on ATM interfaces and for 7x00 serial WAN PAs is well documented. Are there tx-rings or other final interface FIFO buffers applied for serial WAN interfaces on other access routers such as 1700s and 2600s.
Yes, these routers too have tx-rings with FIFO buffers which functions as the hardware queue. I believe that the size of this queue is generally based on the bandwidth of the interface and can be fine tuned in recent IOS releases.
[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...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
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
software switching path. This is not a substitut...
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
