Restricting remote access to management functions
26
NOTE
In RADIUS, the standard attribute Idle-Timeout is used to define the console session timeout value.
The attribute Idle-Timeout value is specified in seconds. Within the switch, it is truncated to the
nearest minute, because the switch configuration is defined in minutes.
Restricting remote access to the device to specific IP addresses
By default, a device does not control remote management access based on the IP address of the
managing device. You can restrict remote management access to a single IP address for the
following access methods:
• Telnet access
• SSH access
• SNMP access
In addition, you can restrict all access methods to the same IP address using a single command.
The following examples show the CLI commands for restricting remote access. You can specify only
one IP address with each command. However, you can enter each command ten times to specify
up to ten IP addresses.
Restricting Telnet access to a specific IP address
To allow Telnet access to the device only to the host with IP address 209.157.22.39, enter the
following command.
PowerConnect(config)# telnet-client 209.157.22.39
Syntax: [no] telnet-client <ip-addr> | <ipv6-addr>
Restricting SSH access to a specific IP address
To allow SSH access to the device only to the host with IP address 209.157.22.39, enter the
following command.
PowerConnect(config)# ip ssh client 209.157.22.39
Syntax: [no] ip ssh client <ip-addr> | <ipv6-addr>
Restricting SNMP access to a specific IP address
To allow SNMP access (which includes Brocade Network Advisor) to the device only to the host with
IP address 209.157.22.14, enter the following command.
PowerConnect(config)# snmp-client 209.157.22.14
Syntax: [no] snmp-client <ip-addr> | <ipv6-addr>
Restricting all remote management access to a
specific IP address
To allow Telnet, and SNMP management access to the device only to the host with IP address
209.157.22.69, enter three separate commands (one for each access type) or enter the following
command.
