Wildcard Characters in Interface Names

With the show interfaces and clear interfaces commands, you can use wildcard characters when specifying interface names (in the interface-name option) to refer to groups of interface names without having to type each name individually. Table 9 lists the available wildcard characters.

You must enclose all wildcard characters except the asterisk in quotation marks (" ").

Table 9: Wildcard Characters for Specifying Interface Names

Wildcard Character

Description

* (asterisk)

Match any string of characters in that position in the interface name. For example, so* matches all SONET/SDH interfaces.

"[character <character...>]"

Match one or more individual characters in that position in the interface name. For example, "so-[03]"* matches all SONET/SDH interfaces in slots 0 and 3.

"[!character <character...>]"

Match all characters except the ones included in the brackets. For example, "so-[!03]"* matches all SONET/SDH interfaces except for those in slots 0 and 3.

"[character1-character2 ]"

Match a range of characters. For example, so-"[0-3]"* matches all SONET/SDH interfaces in slots 0, 1, 2, and 3.

"[!character1-character2]"

Match all characters that are not in the specified range of characters. For example, so-"[!0-3]"* matches all SONET/SDH interfaces in slots 4, 5, 6, and 7.

Wildcard Character	Description
* (asterisk)	Match any string of characters in that position in the interface name. For example, so* matches all SONET/SDH interfaces.
"[character <character...>]"	Match one or more individual characters in that position in the interface name. For example, "so-[03]"* matches all SONET/SDH interfaces in slots 0 and 3.
"[!character <character...>]"	Match all characters except the ones included in the brackets. For example, "so-[!03]"* matches all SONET/SDH interfaces except for those in slots 0 and 3.
"[character1-character2 ]"	Match a range of characters. For example, so-"[0-3]"* matches all SONET/SDH interfaces in slots 0, 1, 2, and 3.
"[!character1-character2]"	Match all characters that are not in the specified range of characters. For example, so-"[!0-3]"* matches all SONET/SDH interfaces in slots 4, 5, 6, and 7.
