If it is just a switch (as in L2 switch) it should not care about IPs - it just switches L2 (ethernet) frames.
Now if you use it as an L3 switch (i.e. like a router) the extra networks mean some more TCAM space will be used for the routes and TCAM space is not an endless resource. But if your switch is so low on TCAM space to cannot afford 16 additional subnets - it should have been replaced very long time ago.
yes,i know,i ask the question is because the colo sales tell me that their tech support say they can not give me more ip because it will let my switch get higher load and low performance(i have only about 10 ip range with them and ask another two,each range is 16 ip only)
How are they giving you these IP ranges? How are they routing the networks towards you? Do they just setup vlans with IP/netmask on each VLAN or do they use your switch as a router for those networks or what? Do you enter IP addresses/networks anywhere in your switch configuration?
Hi,i think they give me the vlan ips directly and the gateway of each vlan are host on their device,and i can use those ip(if a 16 ip range,i can use the 13 ip) for my servers under my switch directly.thanx
