[c-nsp] 3550 as CE

[nasir.shaikh at bt.com]

Arie,
Thanks. No I don't have a subrate link although I do intend to use (an
aggregate) policer on the !G link.
I am currently happily running 12.1(22)EA8 do you think I should upgrade
to 12.2(44)SE? I only need to be able to do QoS marking based on IP
acls.

Nasir,

Be careful about QOS requirements. If your WAN uplink is a subrate link
(i.e. a 1GigE port with an SLAN of <1GigE) you need to perform egress
shaping on that interface, which is not supported on 3550 (or most LAN
switches).

Hi,
Due to the global shortage of 73xx routers I am contemplating to use
some old 3550-12Ts as CE routers on a stie where a connection is
required urgently.
I will be using a fibre link from the local ADM as my WAN link (int
g0/11 or g0/12 on the 3550)

I have enough experience with the 3550 platform EMI with full routing
but have always used it as a CPE behind the CE.

Given the right GBIC, is there any reason why this won't work?
Any experiences that someone would care to share?

Thanks in advance
