time. Use no mac-address age-time command to restore it to default time.
mac-address-table age-time { agetime | disable }
no mac-address-table age-time
Agetime means MAC address aging time which ranges from 1 to 1048575 seconds. Default MAC address
aging time is 300 seconds. Disable means MAC address not aging. Use no command to restore the default MAC
address aging time.
For example :
! Configure MAC address aging time to be 3600 seconds
QTECH(config)#mac-address-table age-time 3600
! Restore MAC address aging time to be 300 seconds
QTECH(config)#no mac-address-table age-time
Display MAC address aging time
show mac-address-table age-time
Use show mac-address-table age-time command to display MAC address aging time.
show mac-address-table age-time
For example :
! Display MAC address aging time.
QTECH(config)#show mac-address-table aging-time
3.6 Configure MAC address item
3.6.1 Add MAC address
MAC address table can be added manually besides dynamically learning.
mac-address-table { dynamic | permanent | static } mac interface interface-num vlan vlan-id
Parameter mac, vlan-id and interface-num corresponded to the three attributions of the new MAC address
table item.
MAC address attribution can be configured to be dynamic, permanent and static. Dynamic MAC address can
be aging; permanent MAC address will not be aging and this MAC address will exist after rebooting; static MAC
address will not be aging, but it will be lost after rebooting.
For example :
! Add mac address 00 : 01 : 02 : 03 : 04 : 05 to be static address table.
QTECH(config)#mac-address-table static 00 : 01 : 02 : 03 : 04 : 05 interface ethernet 0/0/1
vlan 1
3.6.2 Add blackhole MAC address
System can configure MAC address table item to be blackhole item. When the source address or destination
address is blackhole MAC address, it will be dropped.
mac-address-table blackhole mac vlan vlan-id
For example :
! When tagged head of the packet is VLAN 1, forbid packet with its source address or destination address
being 00 : 01 : 02 : 03 : 04 : 05 to go through system
QTECH(config)#mac-address-table blackhole 00 : 01 : 02 : 03 : 04 : 05 vlan 1

- The dr election is available on broadcast nbma interfaces rather than p2p or p2mp interfaces a dr is an interface of a router and belongs to a single network segment the router s 102
- The election votes are hello packets each router sends the dr elected by itself in a hello packet to all the other routers if two routers on the network declare themselves as the dr the router with the higher dr priority wins if dr priorities are the same the router with the higher router id wins in addition a router with the priority 0 cannot become the dr bdr 102

- An igmp snooping enabled switch deems that all its ports on which igmp general queries with the source address other than 0 or pim hello messages are received to be router ports 133
- Basic concepts in igmp snooping 133
- Igmp snooping related ports 133
- Port aging timers in igmp snooping and related messages and actions 133
- Table 1 133
- Whenever mentioned in this document a router port is a port on the switch that leads the switch to a layer 3 multicast device rather than a port on a router 133
- A switch does not forward an igmp report through a non router port the reason is as follows due to the igmp report suppression mechanism if the switch forwards a report message through a member port all the attached hosts listening to the reported multicast 134
- How igmp snooping works 134
- The port aging mechanism of igmp snooping works only for dynamic ports a static port will never age out 134
- When receiving a general query 134
- When receiving a membership report 134
- Address will suppress their own reports upon hearing this report and this will prevent the switch from knowing whether any hosts attached to that port are still active members of the reported multicast group 135
- Processing of multicast protocol messages 135
- When receiving a leave group message 135
- Qtech software configuration manual 137
- Table 2 3 igmp snooping messages 137
- An igmp snooping enabled ethernet switch judges whether the multicast group exists when it receives an igmp leave packet sent by a host in a multicast group if this multicast group does not exist the switch will drop the igmp leave packet instead of forwarding it 138

- Protocol packets of stp 186
- Stp configuration 186
- Why stp 186
- How stp works 187
- Note all the ports on the root bridge are designated ports 187
- Principle for configuration bpdu comparison the configuration bpdu that has the lowest root bridge id has the highest priority if all the configuration bpdus have the same root bridge id they will be compared for their root path costs if the root path cost in a configuration bpdu plus the path cost corresponding to this port is s the configuration bpdu with the smallest s value has the highest priority if all configuration bpdu have the same root path cost they will be compared for their designated bridge ids then their designated port ids and then the ids of the ports on which they are received the smaller the id the higher message priority 189
- Table 2 selection of the optimum configuration bpdu 189
- When the network topology is stable only the root port and designated ports forward traffic while other ports are all in the blocked state they only receive stp packets but do not forward user traffic 190
- In rstp a newly elected designated port can enter the forwarding state rapidly if this condition is met the designated port is an edge port or a port connected with a point to point link if the designated port is an edge port it can enter the forwarding state directly if the designated port is connected with a point to point link it can enter the forwarding state immediately after the device undergoes handshake with the downstream device and gets a response 193
- In rstp a newly elected root port can enter the forwarding state rapidly if this condition is met the old root port on the device has stopped forwarding data and the upstream designated port has started forwarding data 193
- Introduction to mstp 193
- To facilitate description the spanning tree computing process in this example is simplified while the actual process is more complicated 193
- Why mstp 193
- Some concepts in mstp 194
- Currently the device is not capable of recognizing boundary ports when the device interworks with a third party s device that supports boundary port recognition the third party s device may malfunction in recognizing a boundary port 195

- Caution max age is used to configure the longest aging interval of stp lose packet when overtiming the stp will be frequently accounts and take crowded network to be link fault if the value is too small if the value is too large the link fault cannot be known timely max age is determined by diameter of network and the default time of 20 seconds is suggested 2 hello time 1 max age 2 forwarddelay 1 200
