Interfaces

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

Table 13.5. 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.
