The maximum number of ATM ports supported on the AIM-ATM-8 depends on the slot in which the AIM-ATM-8 is installed: • AIM-ATM-8 installed in slot 0-maximum of 12 ATM ports supported • AIM-ATM-8 installed in slot 1-maximum of 8 ATM ports supported 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. controller E1 0/0/0 mode atm aim 1 ! controller E1 0/0/1 mode atm aim 1 ! interface ATM0/0/0 pvc 0/32 12transport ! interface ATM0/0/1 pvc 0/33 12transport ! connection NAME a0/0 0/32 a0/1 0/33 1-26 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide OL-15667-03
