Provides the capability to provide security on the UDP/TCP ports the device uses for management.
The port access security feature is a white list mechanism. If a host’s IP address is not specified in a port-access profile, users from that host cannot access on that port.
The ports used for management are:
telnet, port 23
SSH, port 22
HTTP, port 80
HTTPS, port 443
SNMP, port 161
If you choose to restrict access to the SNMP port then there must be a rule to allow the device its own SNMP access.
By default, port-access profiles do not exist and all ports are open. After a port-access profile is configured for a port all other IP addresses or subnets are blocked. This restriction only takes effect after the first port-access profile is created. Up to 100 port-access profiles can be created on device.
