VLAN Interfaces and MAC Addresses
The device manager uses the HTTP protocol (the default is port 80) and the default method of
authentication (the enable password) to communicate with the switch through any of its Ethernet
ports and to allow switch management from a standard web browser.
If you change the HTTP port, you must include the new port number when you enter the IP address
in the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new
HTTP
port number). You should write down the port number through which you are connected. Use
care when changing the switch IP information.
• If you use Internet Explorer Version 5.5 and select a URL with a nonstandard port at the end of the
address (for example, www.cisco.com:84), you must enter http:// as the URL prefix. Otherwise, you
cannot launch the device manager.
VLAN Interfaces and MAC Addresses
All VLAN interfaces have assigned MAC addresses that are derived from the base MAC address. The
base MAC address is the hardware address that is on the switch label. It also appears when you enter the
show version privileged EXEC command.
On the first VLAN interface (VLAN 1), the MAC address is the base MAC address + 0 x 40. On the next
VLAN interface that you configure, the MAC address is the base MAC address + 0 x 40 +1, and so on
for other VLAN interfaces.
You can enter the show interfaces vlan vlan-id privileged EXEC command to show the MAC and
IP
addresses. The MAC addresses that appear in the show interfaces vlan vlan-id command output are
not the same as the MAC address that is printed on the switch label (the base MAC address).
By default, VLAN 1 is the interface that connects to the management network. When the switch boots
up, the DHCP client (switch) requests an IP address from a DHCP server by using the MAC address of
VLAN 1.
