I have a question about Policy Based Routing (PBR) on MSFC.
Does MSFC1 process Policy Based Routing in software or in hardware ?
What about MSFC3 ?
The background of this question is as follows.
Our customer facing CPU utilization issue on MSFC1. The peak CPU utilization on the MSFC1 become about 30%. Hardware component of that Catalyst 6506 is as follows,
SUP1A : CatOS 5.5(3)
MSFC1 : IOS 12.1(2)E
The MSFC1 is configured with
8 VLAN interfaces
20 static routes (dynamic routing is not operating)
1 named ACL with 16 entries
2 numbered ACL with 50 entries each
I think above configuration does not effect CPU utilization so much. So I am doubting that PBR raises CPU utilization.
The following PBR configured on the MSFC1.
route-map PBR permit 0
match ip address 111
set ip default next-hop xxx.xxx.xxx.xxx
route-map PBR permit 1
match ip address 222
set ip default next-hop yyy.yyy.yyy.yyy
Now customer is thinking of upgrading the Cat6506 to Cat6504-E.
Hardware component of new Catalyst 6504-E is as follows.
SUP720-3B : Cat IOS 12.2(17d)SXB11a
And customer similarly uses same PBR configuration also on new Cat6504/MSFC3.
I understand I should test on both MSFC1 and MSFC3 to compare CPU utilization, however unfortunately I can not prepare those system now. So I posted it becasue I would like to know any information.
Would you please let me know MSFC1 process Policy Based Routing in software or in hardware ?, and what about MSFC3 ?
Your information would be appreciated.
