Restricting remote access to management functions

Restricting remote access to management functions
You can restrict access to management functions from remote sources, including Telnet, the Web
management interface, and SNMP. The following methods for restricting remote access are
supported:
•
Using ACLs to restrict Telnet, Web management interface, or SNMP access
•
Allowing remote access only from specific IP addresses
•
Allowing remote access only to clients connected to a specific VLAN
•
Specifically disabling Telnet, Web management interface, or SNMP access to the device
Using ACLs to restrict remote access
You can use standard ACLs to control the following access methods to management functions on
the device:
•
Telnet access
•
SSH access
•
Web management access
•
SNMP access
To configure access control for these management access methods.
1. Configure an ACL with the IP addresses you want to allow to access the device
2. Configure a Telnet access group, SSH access group, web access group, and SNMP community
strings. Each of these configuration items accepts an ACL as a parameter. The ACL contains
entries that identify the IP addresses that can use the access method.
The following sections present examples of how to secure management access using ACLs. See the
asdf chapter for more information on configuring ACLs.
