Static authentication MAC address by configuring IEEE 802.1x authentication, the switch will not be aging.
Regardless of the device is connected to the switch port happen to the MAC address table MAC address and port
corresponding relationship always will not change, the relationship is completely controlled by the IEEE 802.1X
authentication server. Static MAC address after the switch is powered restart will disappear.
3. Permanent static MAC addresses
permanent MAC address generated through configuration will not be aging, regardless of the device is connected
switches of the change of the port, the MAC address table of MAC address and port of corresponding relation is
always does not change, permanent MAC address does not disappear after the switch is restart
MAC address table can specify the sort type, can choose "auto" and "MAC" two sort types, MAC address and
related forwarding port will be showed in this table. if the status bar displays "certification"
,
shows MAC address
static certification that is not aging treatment, if displays ―static‖ means that MAC address is a permanent
static address that is not aging treatment.
1. The address of the device index according to switch's address, so all MAC address displayed VLAN value is 0.
2. Permanent static address configured in the previous static MAC address port list, need to modify the corresponding item when
port changed.
3. Multicast address list displays the IGMP snooping item, in the address list here all unicast address.
4. MAC address aging time is 300 seconds, the port is disconnected our parent program to clear all the corresponding port items.
5.13 Network Diagnosis
5.13.1 Port mirroring
Port mirroring refers to copy data from the port which need to be monitored to appointed monitoring port for
analysis and monitoring. Ethernet switch supports many-for-one mirror which means messages from several
ports can be copied to a monitored port. User can appoint the direction of monitored message, such as only
monitoring of transmitted messages of appointed port. The device configures port mirroring function through
port mirroring group. Each group includes a monitored port and a group of mirror ports. Total bandwidth of
mirroring is not more than that of monitored port. It is good to monitor and manage its internal network data
when using port mirroring in a company. It is also good to locate the failure when network is cut up.
Example as figure below: Port 4 collects all of the data from port 4 and port 5
