Re: 3825 and 7206 Module

Hi, there are 4, 9, 16, 24 and 36 port switch modules, with and without PoE available for the ISR routers. These are all described in the product section. However these are slightly more expensive than an external switch so most people goes for the latter solution.

The PA you mentioned is the one to terminate E1 data circuits on 7200 routers.

Hope thsi helps, please rate post if it does!

Re: 3825 and 7206 Module


You can insert the HWIC-4ESW directly in the 3825 chassis. Beginning with Cisco IOS 12.3 Mainline and 12.3T, the Cisco Etherswitch modules are supported in IP Base or above.

Alternately, you may use EtherSwitch network modules as well. For comparison refer to the following doc:

Cisco EtherSwitch Modules Comparison

PA-MCX-4TE1 is The is supported in all Cisco IOS® feature sets starting with Release 12.1(5)T. However, with NPE-G2 you would need at least fifth release of 12.4T (ie. 12.4(11)T and above).
