Map ports to ASIC on Cisco 7K
Map Port to ASIC on Cisco 7K Switch
From: Nexus 7000 NXOS VDC Config GuideFind the slot# of the module:
show mod
Enter command:
slot 3 show hardware internal dev-port-map
Sample Output:
--------------------------------------------------------------
CARD_TYPE: 48 port 10G
>Front Panel ports:48
--------------------------------------------------------------
Device name Dev role Abbr num_inst:
--------------------------------------------------------------
> Clipper MAC DEV_ETHERNET_MAC MAC_0 12
> Clipper FWD DEV_LAYER_2_LOOKUP L2LKP 12
> Clipper XBAR DEV_QUEUEING QUEUE 12
> Sacramento Xbar ASIC DEV_SWITCH_FABRIC SWICHF 1
> PHY DEV_PHY PHYS 12
> Clipper L3 Driver DEV_LAYER_3_LOOKUP L3LKP 12

FP port | PHYS | MAC_0 | L2LKP | L3LKP | QUEUE |SWICHF
1 0 0 0 0 0 0
2 0 0 0 0 0 0
3 0 0 0 0 0 0
4 0 0 0 0 0 0
5 1 1 1 1 1 0
6 1 1 1 1 1 0
7 1 1 1 1 1 0
. . .
- Port number = FP port column.
- ASIC = MAC_0 column.
- So, ASIC=int(Port/4) - 1
One port in each
port group can be dedicated to 10Gb using the rate-mode
command.
