Command Attributes
•Management VLAN – This is the only VLAN through which
you can manage the switch. By default, all ports on the switch
are members of VLAN 1, so a management station can be
connected to any port on the switch. However, if you change
the Management VLAN to another VLAN, you will lose access
to the switch unless the management port has already been
configured as a member of the new VLAN. If you lose access,
you can reconnect the management station to a port that is a
member of the Management VLAN or use the console interf ace
to add the management port to the newly configured
Management VLAN. (See “switchport allowed vlan” on
page 129.)
•IP Address Mode – Specifies whether IP functionality is
enabled via manual configuration (Static), Dynamic Host
Configuration Protocol (DHCP), or Boot Pr otocol (BOOTP). If
DHCP/BOOTP is enabled, IP will not function until a reply has
been received from the server. Requests will be broadcast
periodically by the switch for IP configuration se ttings. (DHCP/
BOOTP values can include the IP address, subnet mask, and
default gateway.)
•IP Address – Address of the VLAN interface that is allowed
management access. Valid IP addresses co nsist of four
numbers, 0 to 255, separated by periods. (Default: 0.0.0 .0)
•Subnet Mask – This mask identifies the host address bits used
for routing to specific subnets. (Default: 255.0.0.0)
•Gateway IP Address – IP address of the gateway router
between this device and management stations that exist on
other network segments. (Default: 0.0.0.0)
•MAC Address – The physical layer address for this switch.
