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 3 lists the available wildcard characters.

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

Table 3: 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.
