I am replacing a failing 4500 switche with a newer 4500. This should have been easy but the old switch is using CATOS and the new one has IOS installed. I am slowly recreating the config but have come across something I am not sure about. I have the following line set port channel 2/1-4 183 in the old config. As far as I can see this is aggregating interfaces 2/1-4 is this correct? What does the 183 mean is it just an identifier?
In the router part of the config I have interface Port-channel1.2 and this has an IP address and 802.1q set if I do SH VLAN I can see that this is vlan 2. Can I just use interface vlan 2 and assign it an IP address in IOS?
