Dell S3100 Command Line Reference Guide for the Series 9.100.1 - Page 1512

Version E-Series legacy command Description 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. Related Commands • show snmp engineID - displays the SNMP engine and all the remote engines that are configured on the router. • show running-config snmp - displays the SNMP running configuration. snmp-server group Configure a new SNMP group or a table that maps SNMP users to SNMP views. 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 accesslist-name | ipv6 access-list-name | access-list-name ipv6 access-list-name]] command. Parameters group_name 1 | 2c | 3 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/securitynames (defaults): • v1v2creadg - maps to a community/security-name with ro permissions. • 1v2cwriteg - maps to a community/security-name rw permissions. (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. The default is 1. auth noauth priv (OPTIONAL) Enter the keyword auth to specify authentication of a packet without encryption. (OPTIONAL) Enter the keyword noauth to specify no authentication of a packet. (OPTIONAL) Enter the keyword priv to specify both authentication and then scrambling of the packet.
