Maximum Number Of Supported Atm Ports; Atm Cell Switching - Cisco 3825 Software Configuration Manual

New Features in Cisco IOS Release 12.4(16)MR1
PW Redundancy With PW Class

Maximum Number of Supported ATM Ports

This enhancement increases the maximum number of supported ATM ports on the Cisco 3825 router.
The maximum number of ATM ports supported on the AIM-ATM-8 depends on the slot in which the
AIM-ATM-8 is installed:
•
•
The ATM-AIM module still supports a maximum of 4 ATM ports.

ATM Cell Switching

This feature provides PVC-to-PVC cell switching on the Cisco 3825 router.
The feature includes PVC remapping within either an AIM-ATM module or AIM-ATM-8 module. Also,
the feature is available for PVC-to-PVC switching between ATM interfaces and/or ATM IMA groups.
Note that PVC values must be above the well-known virtual path identifier/virtual channel identifier
(VPI/VCI) range (0/32).
The following configuration snippet shows a connection from ATM0/0/0 to ATM0/0/1. The PVC is
mapped from 0/32 to 0/33 and vice versa.
