Page 3 | AlliedW are Plus™ OS Ho w T o Note: Switching Port Numbering P ort Numbering P or t n umbers In the AlliedW are Plus OS, sw itch por ts ar e named po rt x.y.z (e.g. por t 1 .0. 1 ), where: z the first number ( x ) is the stack ID number z the second number ( y ) is the module n umber .
Page 4 | AlliedW are Plus™ OS Ho w T o Note: Switching Port Numbering Po r t r a n g e s Continuous T o configur e a continuous range of ports at th e same time, enter the range in either of the form ats: port x.
Page 5 | AlliedW are Plus™ OS Ho w T o Note: Switching Port speed, duplex mode, and polarity P ort speed, duplex mode , and polarity In most netw orks, you will not need to chan ge the por t speed, duplex mode, or polarity , because the ports automatically negotiate suitable settings.
Page 6 | AlliedW are Plus™ OS Ho w T o Note: Switching Port speed, duplex mode, and polarity Ho w to set the duplex mode By default, ports autonegotiate duplex mode (except for 1 00Base-FX por ts which do not support autonegotiation, so de fault to full duplex mode).
Page 7 | AlliedW are Plus™ OS Ho w T o Note: Switching Basic VLAN and IP configuration Basic VLAN and IP configuration This section configures a s witch in a simple four -VLAN network, shown in the f ollowing figure. In this netw ork, VLANs 2-4 span tw o switches.
Page 8 | AlliedW are Plus™ OS Ho w T o Note: Switching Basic VLAN and IP configuration VLANs ar e configured as an attribute of switch ports. This means that you g o into Interface Configuration mode to configur e the switch ports, and specif y the VLANs you w ant to associate with each switch port.
Page 9 | AlliedW are Plus™ OS Ho w T o Note: Switching Basic VLAN and IP configuration Change to configuring vlan 1 by entering the command: awplus(config-if)#interface vlan1 Assign the IP addr ess and su bnet by entering the command: awplus(config-if)#ip address 192.
Page 10 | AlliedW are Plus™ OS How T o Note: Switching Basic VLAN and IP configuration T o check the configuration, first return to Privileged Ex ec mode by entering the command: awplus(config)#exit.
Page 11 | AlliedW are Plus™ OS How T o Note: Switching Basic VLAN and IP configuration T o see VLAN interface details, enter the command: awplus# show interface | begin vlan The output looks lik e this: Interface vlan1 Scope: both Link is UP, administrative state is UP Hardware is VLAN, address is 0000.
Page 12 | AlliedW are Plus™ OS How T o Note: Switching Rapid Spanning T r ee Protocol (RSTP) Rapid Spanning T r ee Pr otocol (RSTP) This example tak es the network fr om "Basic VLAN and IP configuration" on page 7 and adds two mor e switches in a ring topology , as the following figure shows.
Page 13 | AlliedW are Plus™ OS How T o Note: Switching Rapid Spanning T r ee Protocol (RSTP) T o see the STP state, ente r Privileged Exec mode and enter the command: awplus#show spanning-tree The output looks lik e this: Note that the Bridge ID is 8000000 0cd24033 1 , and that other IDs follow the same pattern.
Page 14 | AlliedW are Plus™ OS How T o Note: Switching Rapid Spanning T r ee Protocol (RSTP) Ho w to change the r oot bridge priority The default r oot bridge priority is 32768 (8000 in hexadecimal). When all sw itches ha ve the same priority , the s witch with the lowe st MA C address becomes the r oot bri dge.
Page 15 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) Multiple Spanning T r ee Protocol (MSTP) This example takes the looped netw ork fr om "Rapid Spanni ng T ree Pr otocol (RSTP)" on page 12 and configures MSTP instea d of RSTP .
Page 16 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) Po r t s 1 .0.2- 1 .0.4 are in access mode. Enter the commands: awplus(config-vlan)#interface port1.0.2 awplus(config-if)#switchport access vlan 2 awplus(config-if)#interface port1.
Page 17 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) Enter Interface Configuration mode for the trunk ports 1 .
Page 18 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) T o check for general information about MSTP , and the CIST settings, enter Privileged Ex ec mode and enter the command: awplus#show spanning-tree The output shows that Switch 3 is the CIST root br idge: 7.
Page 19 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) T o check for the state of each port for each instance, enter Privilege d Exec mode and enter the command: awplus#show spanning-tree mst instance < value > interface port< value > For instance 1 and port 1 .
Page 20 | AlliedW are Plus™ OS How T o Note: Switching Multiple Spanning T ree Pr otocol (MSTP) For instance 1 and port 1 .0.6 —vlan2 and vlan3—the output shows that the port is forwarding pack ets. The po rt role is r ootpor t , indicating that it is the shortest path to the root bridge for the AlliedW are Plus switch.
Page 21 | AlliedW are Plus™ OS How T o Note: Switching Link Aggregation Link Aggr egation This section has examples of two wa ys to aggregate ports together : z dynamically using LA CP z statically , on pag e 24 Both examples configure the AlliedW are Plus sw itch that is shown in the following figur e .
Page 22 | AlliedW are Plus™ OS How T o Note: Switching Link Aggregation Po r t s 1 .0.2- 1 .0.4 are in access mode. Enter the commands: awplus(config-vlan)#interface port1.0.2 awplus(config-if)#switchport access vlan 2 awplus(config-if)#interface port1.
Page 23 | AlliedW are Plus™ OS How T o Note: Switching Link Aggregation For detailed information about a port ( 1 .0.5 in this case), enter the command: awplus#show port etherchannel port1.
Page 24 | AlliedW are Plus™ OS How T o Note: Switching Link Aggregation Ho w to configure static a ggregation This section describes how to use statically-aggr egated por ts instead of LA CP . For the network diagram, see page 21 . First cr eate the VLANs and associat e them with por ts, by f ollowing step 1 on page 21 and step 2 on page 22 .
Page 25 | AlliedW are Plus™ OS How T o Note: Switching Por t mir ror ing Po r t m i r r o r i n g This example shows how to send por t 1 .0.23 a cop y of all traffic that ingresses and egresses port 1 .0.2. In other words, port 1 .0.23 is the mirr or por t, and port 1 .
