Re: Etherchannel plus routing at the same time?
One's Too Many wrote:
The central site has a C3750 switch, which right now I'm also using to
handle some static routing, so the port which is connected to an
offsite C2950 switch is set to "no switchport" and has an IP address
nailed to it. Routing is working well. There are two identical 100Mbps
fiber optic lines and sets of media converters going to the C2950 at
the remote site, so what I'd like to know is if it is possible to bond
two ports in each switch together in an etherchannel, yet still keep a
nailed IP address on the etherchannel at the C3750 switch since it
would be acting as like a router's interface port?
Yes, why not.
I had once tried creating a separate vlan on the C3750, assigning the
IP address to that vlan, and making the fast ethernet port which is
connected to the fiber link into a member of that vlan. Routing worked
ok, but thruput to the remote site dropped dramatically. It seems that
routing the vlan was much slower than routing an individual hardware
10/100 port on the C3750.
Did You see any info in logs? From Your desciption it looks like
load-balanced traffic was not CEF-switched, thus lacked ASIC-powered
speed. Can You show `sh cef not-cef-switched' after You configure
the 3750 for such topology and test it with some traffic? Also, how
exactly did look Your configuration regarding port-channel, SVI and
physical ports in this routed VLAN?
