what is different between cisco router and layer 3 switch
Answer Posted / dharmendra kumar soni
1> L3 switches do not have WAN interfaces.
2> we can connect Ethernet circuits to a switch so you only
need a router.
3> As far as I know Call Manager Express does not run on a
switch but does on a router.
4>L3 Switch do switching at layer 3 by preserving the source
and destination mac.
5>router do normal routing lookup.
6>Switches doesnt support some QoS features.
7>Switches doesnt support NAT.
8>The forwarding packet on switches is done on ASIC
(Application Specific Integrated Circuits)
9>which is done in hardware rather than a software.
10>Forwarding packet on routers are done in a software.
11>router supports different WAN technologies unlike switches.
12>We can not implement routing on cisco layer switch.
13> We can not connect ISP directly to cisco layer 3 switch.
I think this is some main difference between router and switch.
Thanks,
