익스트림 스위치 STP 설정
구성은 아래 그림과 같으며, STP는 CATS vlan 만 가지고 설정하기때문에, EXSwitch-R과 EXSwitch-2는 연결되지 않았다고 생각해야한다.(DOGS vlan 포트로 연결되어 있으므로). 이것은, 현재 내가 구성한 GNS3 exos vm에서 vlan tagging이 되지 않는 문제 때문이다.
익스트림 스위치가지원하는 stp 종류는 아래와 같다.
802.1d – STP 표준으로 느림.
802.1w – RSTP
mstp – multiple stp
확인
EXSwitch-R.7 # configure stpd s0 mode ? dot1d 802.1d mode dot1w 802.1w mode mstp mstp mode
RSTP(Rapid STP)로 설정 진행
EXSwitch-R 설정
* EXSwitch-R.12 # disable stpd s0 * EXSwitch-R.13 # configure stpd s0 mode dot1w
CATS vlan의 모든 포트가 STP 도메인에 추가되도록 설정한다.
* EXSwitch-R.16 # enable stpd "s0" auto-bind vlan CATS
확인해 보면, auto-bind로 설정했기 때문에, VLAN에 할당하지 않은 11,12번 포트토 stp 도메인에 추가되어 있다.

stp도메인에서 원하지 않는 11-12포트 제거한다.

* EXSwitch-R.32 # enable stpd s0
EXSwitch-1의 STP 설정
STP를 원하는 CATS vlan과 포트만 stp도메인에 참여시키도록 한다.
* EXSwitch-1.4 # configure stpd s0 mode dot1w * EXSwitch-1.5 # configure stpd s0 add CATS ports 1-4 * EXSwitch-1.6 # sh stpd s0 Stpd: s0 Stp: DISABLED Number of Ports: 4 Rapid Root Failover: Disabled Operational Mode: 802.1W Default Binding Mode: 802.1D 802.1Q Tag: (none) Ports: 1,2,3,4 Participating Vlans: CATS Auto-bind Vlans: Default Bridge Priority : 32768 Bridge Priority Mode: 802.1t Operational Bridge Priority: 32768 BridgeID : 80:00:00:53:5b:62:8f:00 Designated root : 00:00:00:00:00:00:00:00 RootPathCost: 0 Root Port : ---- MaxAge : 0s HelloTime : 0s ForwardDelay : 0s CfgBrMaxAge : 20s CfgBrHelloTime: 2s CfgBrForwardDelay: 15s Topology Change Time : 35s Hold time : 1s Topology Change Detected : FALSE Topology Change : FALSE Number of Topology Changes : 0 Time Since Last Topology Change: 0s Topology Change initiated locally on Port none Topology Change last received on Port none from none Backup Root : Off Backup Root Activated : FALSE Loop Protect Event Window : 180s Loop Protect Threshold : 3 New Root Trap : On Topology Change Trap : Off Tx Hold Count : 6 * EXSwitch-1.7 #

edge-safeguard를 위한 edge포트 설정
* EXSwitch-1.9 # configure stpd s0 ports edge-safeguard enable 3-4 bpdu-restrict recovery-timeout 60
EXSwitch-3의 설정
* EXSwitch-2.3 # configure stpd s0 mode dot1w * EXSwitch-2.4 # configure stpd s0 add CATS ports 1-4 * EXSwitch-2.5 # enable stpd * EXSwitch-2.6 # configure stpd s0 ports edge-safeguard enable 3-4 bpdu-restrict recovery-timeout 60
확인
CATS VLAN을 보면, EXSwitch-1과 EXSwitch-2 사이에 루프가 발생하고 있다. 이 점을 확인하고, STP 상태를 확인해 보면,
EXSwitch-1에서 stp 상태를 확인해 보면 아래와 같다.
