Usage
Information Changing the value of the SNMP Engine ID has important side effects. A user’s
password (entered on the command line) is converted to a message digest
algorithm (MD5) or secure hash algorithm (SHA) security digest. This digest is based
on both the password and the local Engine ID. The command line password is then
destroyed, as required by RFC 2274. Because of this deletion, if the local value of
the Engine ID changes, the security digests of SNMPv3 users is invalid and the users
will have to be reconfigured.
For the remote Engine ID, the host IP and UDP port are the indexes to the
command that are matched to either overwrite or remove the configuration.

snmp-server group
Configure a new SNMP group or a table that maps SNMP users to SNMP views.
Z9500
Syntax snmp-server group [group_name {1 | 2c | 3 {auth | noauth |
priv}}] [read name] [write name] [notify name] [access access-
list-name | ipv6 access-list-name | access-list-name ipv6
access-list-name]]
To remove a specified group, use the no snmp-server group [group_name
{v1 | v2c | v3 {auth | noauth | priv}}] [read name] [write
name] [notify name] [access access-list-name | ipv6 access-
list-name | access-list-name ipv6 access-list-name]] command.
Parameters group_name Enter a text string (up to 20 characters long) as the name of
the group. The following groups are created for mapping to
read/write community/security-names (defaults):
•v1v2creadg — maps to a community/security-name
with ro permissions.
•1v2cwriteg — maps to a community/security-name rw
permissions.
1 | 2c | 3 (OPTIONAL) Enter the security model version number (1, 2c,
or 3):
•1 is the least secure version.
•3 is the most secure of the security modes.
•2c allows transmission of informs and counter 64, which
allows for integers twice the width of what is normally
allowed.
