1841 AIM module question

[dtushing123]

What is the difference between the onboard VPN module and adding an AIM module to an 1841 ?

If I do not install an AIM module I get

Cisco 1841 (revision 7.0) with 235520K/26624K bytes of memory.

Processor board ID FTX1127W1AH

2 FastEthernet interfaces

1 terminal line

1 Virtual Private Network (VPN) Modules

If I install the AIM I get the AIM light lit and the following

Cisco 1841 (revision 7.0) with 235520K/26624K bytes of memory.

Processor board ID FTX1127W1AH

2 FastEthernet interfaces

1 terminal line

2 Virtual Private Network (VPN) Modules

Therefore I am wondering do I even need to add the AIM card to this router or is one built in ?

Thanks

Darren

Darren,

The 1841 does have an onboard crypto accelerator. Depending on the model of AIM, it can offer some or all of the following additional benefits:

IPPCP Hardware Acceleration

IPv6 IPSec

Cisco IOS WebVPN or SSL VPN

Cisco IOS Secure Multicast

See Table 1 of the following link.

The AIM-VPN/SSL also offloads termination of SSL tunnels from the router CPU. See the note below Table 1 in the link above.

Hope this helps. If so, please rate the post.
