The interface is regarded by the operating system as an Ethernet-like device like other Ethernet devices. It also provides
an Entry to SNMP providing basic information about traffic through the interface. This command shows the basic
information about byte and packet traffic through the interface, in SNMP terms.
13.7.24. user
Syntax:
user add <name> [pwd <passwd> [pap|chap]]
user [<name>]
user delete <name>|all
Description:
This command stores information about a particular login name/password combination. This is referred to as a ‘
user
’,
regardless of whether it represents an individual. When
user
is called on its own, information about all existing users is
listed. When
user <name>
is called with no further arguments, details of that user alone are printed. Passwords are not
shown.
Use
user delete
to delete an individual user by name, or to delete all users.
Use
user add <name>
to create a new user or update an existing one. The password is stored, and the authentication
protocol which must be used for this user.
If a user is deleted or changed, existing sessions are not affected.
Configuration saving saves this information.
13.8. Commands for SNMP configuration
13.8.1. access
Syntax:
access [read | write] <community> [<IP addr>]
access delete <community> [<IP addr>]
access flush
access list
Description:
The “read” and “write” options configure a community name that can be used for read-only or read-write access,
respectively. If an IP address is specified, then the community name is valid only for SNMP requests issued from that IP
address. (It should be noted that this can be rather weak security, since it is possible for the source address of IP packets
to be forged.) The same community name can be configured several times with different IP addresses, to allow access
with the same community name from a number of different machines. The number of access records (community names
paired with optional IP addresses) that can be configured is limited only by available memory.
The “delete” option deletes an access record. The IP address must match exactly; if it is not specified, only a matching
access record that has no IP address will be deleted. The “flush” option deletes all access records. The “list” option
lists the access records.
Configuration saving saves the access records.
By default, if there are no access records in the
snmpinit
file, no SNMP management is allowed.
