Hi to all,
I read about CEF and it has to be enable in order to do per-packet load balancing (PPLB). However, while it works fine on routers, i dont know if CEF allows PPLB on multilayer switches. I came across this bit of info from a document entitled "Configuring Cisco Express Forwarding" [XC-29-XC-32, Cisco IOS Switching Services Configuration Guide]
"Note Per-packet load balancing via CEF is not supported on Engine 2 Gigabit Switch Router (GSR) line cards (LCs)."
Can someone pls explain the above statement to me. I understood it as saying that PPLB via CEF is not allowed on multilayer switches. Is there a document that states whether PPLB via CEF is allowed on multilayer switches?
One thing more, what is the maximum number of Fast Ethernet ports in existing Cisco routers?Which Cisco router is that?
