show snmp access

Use the show snmp access command to display SNMP access information.

Syntax Description

Default

The default storage type is volatile.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

If you use special characters for the groupname and username (nonprintable delimiters for these parameters), you must use a hexadecimal keyword, which is one or two hexadecimal digits separated by a colon (:); for example, 00:ab:34.

The read-only keyword is supported for security model v3 only.

• show cam system

• show flash

• show memory buffers

• show microcode

• show module

• show proc

• show proc mem

• show proc cpu
