I have some confusion about some hardware components. I watched the video datasheet of cisco routers and switches.
In cisco 2901 and 2911 models of routers there is service module . What is meant by service module. what does it do ?
If we buy a new 6500 switch, what are the components we get bydefault. Is there any special configuraton to be done for 6500 . like Sup engine config etc. What is the difference between ASIC and Sup engine ?
In which slots, we need to insert Supervisor Engine ? does it vary with the model . (6503, 6505, 6509, 6513 etc).
What is meant by service module. what does it do ?
In general it is an add on hardware to the routers to provide support for additional services like -Terminating your T1/T3 links, Voice ports etc (in the case of 29xx). Check the below link to get more idea.

That would be like flying a Piper Cherokee with a pilot, a co-pilot and a flight attendant.
Laugh - well in a Piper Cherokee there can be a reason. Suppose two of the flight crew are trying to qualify for the MHC, someone needs to fly the plane (as many smaller Piper Cherokees don't have auto pilots).
You're right about the limitation of 2 sups in a 6500 but some large chassis designs can use more than 2 sups or processing engines to increase forwarding performance.

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
