it can get a bit confusing at times, but in general, all Cisco euipment
eventually has hardware (and software)limitations that eventually come into
play.
Yes MQC is supported. So far as I can tell, all functionality is supported
with the obvious exceptions. No frame relay traffic shaping, for example.
The 3550 is a fixed configuration box. No upping the RAM or flash. What you
see is what you get.
You can use one of the four ( five now? This mayu have changed with the new
IOS ) SDM's.
Switch_48#sh sdm prefer
The current template is the default template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1K VLANs.
number of unicast mac addresses: 5K
number of igmp groups: 1K
number of qos aces: 1K
number of security aces: 1K
number of unicast routes: 8K
number of multicast routes: 1K
Switch_48#
Switch_48(config)#sdm ?
prefer Config TCAM and ASIC RAM size. Warning: need to reset switch for
configuration to take effect.
Switch_48(config)#sdm prefer ?
access multicast and qos/acl bias, drop unicast
extended-match Using extended match for unicast routing
routing unicast bias, drop qos/acl
vlan vlan bias, drop routing
There is a section in the documentation that covers this.
As far as queues and things, gotta read the docs carefully. IIRC, it is not
all in the same place, so you have to dig around a little.
contact me off line. perhaps something can be worked out.
