Command History
Usage Guidelines The macro name is a 32-character maximum character string.
A macro can contain up to five ranges.
All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet ports,
all EtherChannel ports, or all VLANs, but you can combine multiple interface types in a macro.
When entering the interface-range, use this format:
type {first-interface} - {last-interface}
You must add a space between the first interface number and the hyphen when entering an
interface-range. For example, fastethernet0/1 -2 is a valid range; fastethernet0/1-2 is not a valid
range.
Valid values for type and interface:
vlan vlan-id, where vlan-id is 1 to 4094.
port-channel port-channel-number, where port-channel-number is 1 to 6
fastethernet interface-id
gigabitethernet interface-id
longreachethernet interface-id
VLAN interfaces must have been configured with the interface vlan command (the show
running-config privileged EXEC command displays the configured VLAN interfaces). VLAN
interfaces not displayed by the show running-config command cannot be used in interface-ranges.
macro-name Name of the interface-range macro; up to 32 characters.
interface-range Interface range; for valid values for interface ranges, see “Usage Guidelines.”
