Remote access to management function restrictions
Remote access to management function restrictions
You can restrict access to management functions from remote sources, including Telnet and SNMP.
The following methods for restricting remote access are supported:
• Using ACLs to restrict Telnet or SNMP access
• Allowing remote access only from specific IP addresses
• Allowing Telnet and SSH access only from specific MAC addresses
• Allowing remote access only to clients connected to a specific VLAN
• Specifically disabling Telnet or SNMP access to the device
The following sections describe how to restrict remote access to a Brocade device using these
methods.
