7200 bandwidth points help

prakadeesh · ‎10-15-2009

Hello All,

I have a 7206VXR router. I have a small confusion with the bandwidth points that I am getting when i Give a show vers.

show version (chopped):

Cisco IOS Software, 7200 Software (C7200P-IPBASE-M), Version 12.4(4)XD10, RELEASE SOFTWARE (fc2)

Technical Support: http://www.cisco.com/techsupport

Compiled Fri 28-Dec-07 14:12 by karnagar

ROM: System Bootstrap, Version 12.4(12.2r)T, RELEASE SOFTWARE (fc1)

BOOTLDR: Cisco IOS Software, 7200 Software (C7200P-BOOT-M), Version 12.4(4)XD10, RELEASE SOFTWARE (fc2)

System image file is "disk2:c7200p-ipbase-mz.124-4.XD10.bin"

Cisco 7206VXR (NPE-G2) processor (revision A) with 917504K/65536K bytes of memory

PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.

Current configuration on bus mb2 has a total of 600 bandwidth points.

This configuration is within the PCI bus capacity and is supported.

issue:

mb2 bus shows 600 points as current config:

now the cards i have is slot 2,4 and 6 are :

show diag of 2,4 and 6 :

Slot 2:

Dual Port FastEthernet (RJ45) Port adapter, 2 ports

Port adapter is analyzed

Product (FRU) Number : PA-2FE-TX

Top Assy. Part Number : 800-08350-06

EEPROM format version 4

Slot 4:

Fast-ethernet (TX-ISL) Port adapter, 1 port

Port adapter is analyzed

FRU Part Number: PA-FE-TX

Slot 6:

Mx serial Port adapter, 4 ports

Port adapter is analyzed

EEPROM contents at hardware discovery:

Hardware revision 1.0

Part number 73-1577-04

FRU Part Number: PA-4T+=

so slot 2 : PA-2FE-TX(400 ponits but one port shut down so shld be 200)

slot 4: PA-FE-TX = 200

slot 6 : PA-4T+ = 0

so total should be 400 but show version shows 600, one port in the slot 2 PA-2FE-TX is shut down now.

please help, why I am getting a 200 point extra?

Hello Prakadeesh,

>> so slot 2 : PA-2FE-TX(400 ponits but one port shut down so shld be 200)

I may be wrong but I think BW points are calculated on PA type not how many ports are active and configured.

https://www.cisco.com/en/US/prod/collateral/routers/ps341/prod_presentation09186a008009184d.pdf

also you need to consider that ports on the NPE uses BW points on one bus and this can make the difference you see.

For this reason, someone prefers 7204 chassis over 7206 chassis

Hope to help

Giuseppe

Hi,

PA-2FE-TX is 400 bandwidth points, it doesn't mean you shut down one port, and it will decrease to 200. You can try to shut down both ports, it still 400.

Thanks,

Ken

thanks everyone :)

I was under the impression that one port use will halve the BW points..
