Re: [H/W] VS-S720-10G-3CXL Well the thing is that some of the distro switches are single link back to one of the Cores, others have a link to both, one disabled.
I'll take a look and see.
Not going to be able to post a sanitized config (infosec policy), but I'll tell you what I can:
3 48 Port Copper Blades per chassis (WS-X6748-GE-TX)
2 Fabric-Enabled 48-Port Small Form-Factor Pluggable (SFP)-Based Gigabit Ethernet Module (WS-X6748-SFP)
30 Static Routes
15 Access Lists
2 Instances of EIGRP
Spanning-Tree (no loops)
Can you provide interface configuration information for the interface vlan's? There is nothing security related in those. Confirm that proxy arp is disabled, no ip redirects, no ip directed broadcast, etc. Anything there that could possibly be an obvious source of additional processor time. (on top of all the other showcmds and troubleshooting from the link above)
I can try.
We do have proxy arp disabled, but ip redirects and directed broadcast traffic are used (at least to my knowledge).
