We are planing replace 6509 to 4900M+Nexus5548 due to A/C and Power issue. We have two 6509s and plan to use two 4900M (20xRJ45 and 8x10G modules) + two Nexus5548 to replace it.
(4900M Layer 3 and do HSRP, 5548 for 1G and 10G layer 2 connections)
Current 6509 CPU usage is very low. We have around 300 servers.
Could you kindly provide some advices. Appreciate !
The 5k can do PBR. See the configuration guide section here.
As noted already, the L3 card and appropriate license need to be used to fully avail oneself of the 5K's L3 features.
That said, I prefer to do edge (MPLS WAN or Internet) routing on a dedicated IOS router (i.e. an ISR G2 or ASR). It just give more flexibility and there's none of the minor (and some not so minor) caveats of the various routing protocols supported on NX-OS.
