SSH Overview
The Secure Shell (SSH) protocol provides secure Telnet between a client and the switch. By
default, SSH is disabled on the switch.
The switch can support up to two concurrent SSH sessions.
Configuring SSH
MAC Address Settings
MAC address settings configuration provides for the ability to:
• Configure a timeout period for aging learned MAC addresses
• Limit specified layer two multicast addresses to specific ports within a VLAN
• Enable the ability to treat static unicast MAC addresses as a multicast address
Age Time
Learned MAC addresses can be assigned an age in seconds after which they will be flushed from
the FID. The default value is 300 seconds.
Use the set mac agetime command to configure the MAC age-time for MAC addresses.
The following example sets the age-time for MAC addresses on this device to 600 seconds:
C5(rw)->set mac agetime 600
C5(rw)->show mac agetime
