C3750X ASIC mapping + buffer space

Unanswered Question
Sep 8th, 2010

Hello Forum,

1) Can someone post the output of a "sh platform pm if-numbers" command for

WS-C3750X 24-port and 48-port models to see the ASIC mappings ?

2) How many ASICs does this switch have ?

3) Is the buffer space still 2MB per ASIC ?



I have this problem too.

WS-C3750X 24-port have 1 port asic

48 ports switch have 2 port asic.

"show platform pm if-numbers" shows the pysical port interface mapped to what ASIC

"show platform pm platform-block" to see corresponding mapping between the physical port interface and the ASIC/port number.

"show mls qos input-queue to see output of total input-queues supported.

The ingress queue has a total of 4 queues. The first 2 are used internally by the syste. for inter-stack commmunication and priority packets. out of 4 quues, only 2 quues may be configured.

The egress queue also offers 4 queues per port.
