VSS(Virtual Switching System) används för att göra två stycken fysiska switchar till en logisk. Med detta så slipper man HSRP samt VRRP
Installation
Man behöver 2st cisco 4500-x, 4500-e eller 6500-e i -e modellerna så behövs Cisco Catalyst Supervisor Engine 7-E eller 7-LE men den är inbyggd i -x modellen
Konfiguration
sätt Virtual Switch domain samt switch nummer
SW1#conf t Enter configuration commands, one per line. End with CNTL/Z. SW1(config)#switch virtual domain 10 Domain ID 10 config will take effect only after the exec command 'switch convert mode virtual' is issued SW1(config-vs-domain)#switch 1 SW1(config-vs-domain)#exit SW1(config)#
SW2#conf t Enter configuration commands, one per line. End with CNTL/Z. SW2(config)#switch virtual domain 10 Domain ID 10 config will take effect only after the exec command 'switch convert mode virtual' is issued SW2(config-vs-domain)#switch 2 SW2(config-vs-domain)#exit SW2(config)#
Konfigurera VSL Port Channel
SW1(config)#int port-channel 5 SW1(config-if)#switchport SW1(config-if)#switch virtual link 1 SW1(config-if)#no shut SW1(config-if)#exit *Jan 24 05:19:57.092: %SPANTREE-6-PORTDEL_ALL_VLANS: Port-channel5 deleted from all Vlans
SW2(config)#int port-channel 10 SW2(config-if)#switchport SW2(config-if)#switch virtual link 2 SW2(config-if)#no shut SW2(config-if)#exit SW2(config)# *Jan 24 05:14:17.273: %SPANTREE-6-PORTDEL_ALL_VLANS: Port-channel10 deleted from all Vlans
Konfigurera VSL portarna
SW1(config)#int range gig7/3 - 4 SW1(config-if-range)#switchport mode trunk SW1(config-if-range)#channel-group 5 mode on WARNING: Interface GigabitEthernet7/3 placed in restricted config mode. All extraneous configs removed! WARNING: Interface GigabitEthernet7/4 placed in restricted config mode. All extraneous configs removed! SW1(config-if-range)#exit
SW2(config)#int range gig4/45 - 46 SW2(config-if-range)#switchport mode trunk SW2(config-if-range)#channel-group 10 mode on WARNING: Interface GigabitEthernet4/45 placed in restricted config mode. All extraneous configs removed! WARNING: Interface GigabitEthernet4/46 placed in restricted config mode. All extraneous configs removed! SW2(config-if-range)#exit
Switcha över till VSS från vanlig
SW1#switch convert mode virtual
SW2#switch convert mode virtual
Kolla så att det fungerar
SW1#sh switch virtual Executing the command on VSS member switch role = VSS Active, id = 1 Switch mode : Virtual Switch Virtual switch domain number : 10 Local switch number : 1 Local switch operational role: Virtual Switch Active Peer switch number : 2 Peer switch operational role : Virtual Switch Standby Executing the command on VSS member switch role = VSS Standby, id = 2 Switch mode : Virtual Switch Virtual switch domain number : 10 Local switch number : 2 Local switch operational role: Virtual Switch Standby Peer switch number : 1 Peer switch operational role : Virtual Switch Active
Felsökning
Kör sh switch virtual och kolla så det ser ut som det gör i konfigurationssteget.
Tips N Trix
Man kan använda sig av 10ge interface också och inte enbart 1ge som står i guiden. Kommando för att byta vilken switch som är aktiv.
