hi every body !
i have few questions regarding ip address assignment on cisco cat switch.
ip address on cisco switch can be configured in following ways:
switch(config)# ip address 220.127.116.11. 255.255.255.0
Switch(config) interface vlan 1
switch(config-vlan1) ip address 18.104.22.168 255.255.255.0
now my question is how does configuring ip address using these two methods affect switch ?
my second question is about vlans and ip address.
let say i have a cisco cat switch with two vlans.
switch(config) interface vlan 1
switch(config-vlan1) ip address 22.214.171.124 255.255.255.0
switch(config) interface vlan2
switch (config-vlan2)ip address 126.96.36.199 255.255.255.0
my question is when should we assign each vlans on the switch different ip?
I didn't know there was a config level option for ip address, I always assumed the "ip address" command had to be on an interface.
In your example of the two vlans, you are creating two layer 3 vlans by assigning an IP address to each vlan. In that example, vlan 1 will be able to route to vlan 2 (assuming you enable "ip routing").
