[C9800CL][#8]- Data Interface Redundancy - Port Channel

안녕하세요.

 

오늘은  C9800에 Data Interface 2개를 Port Channel로 구성하는 방법에 대해서 알아보겠습니다.

WLC01: Gi3 - MGMT IP vrf MGMT

G1 and G2 -  Portchannel 01로 묶고 Trunk 포트로 모든 VLAN를 허용 하게 설정 하겠습니다.

 

1. WLC GUI에 접속합니다.

 

Gi1/Gi2를 아래와 같이 설정합니다.

 

2. Port-channel를 설정합니다. 

 

SW01(config)#int ra g1/0, gi0/3            SW01(config-if-range)#channel-group 1 mode on SW01(config)#int po 1 SW01(config-if)#sw tr en dot1q  SW01(config-if)#sw mo trunk

 

Interface Status 확인

SW01#show int status Port      Name               Status       Vlan       Duplex  Speed Type  Gi0/0                        connected    trunk        auto   auto unknown Gi0/1                        connected    trunk        auto   auto unknown Gi0/2                        connected    100          auto   auto unknown Gi0/3                        connected    trunk        auto   auto unknown Gi1/0                        connected    1            auto   auto unknown Gi1/1                        connected    10           auto   auto unknown Gi1/2                        connected    20           auto   auto unknown Gi1/3                        connected    100          auto   auto unknown Po1                          connected    trunk        auto   auto  SW01#

 

 

테스트를 위해서 WLC 아래와 같이 설정 합니다.

VLAN 110

VLAN 120
VLAN 130

SVI 110 - 192.168.110.254

SVI 120 - 192.168.120.254

SVI 130 - 192.168.130.254

 

VLAN 110를 설정합니다. 그리고 아래 사진처럼 VLAN 120, VLAN 130도 설정 합니다. 

 

 

2. SVI를 설정 합니다.

 

아래 사진처럼 SVI 120과 SVI 130도 설정 합니다. 

 

 

Cisco switch에서 

VLAN 110,120,130설정하고 SVI 110,120,130를 설정합니다.

SVI 110: 192.168.110.253

SVI 120: 192.168.120.253

SVI 130: 192.168.130.253
