WLC 5508 interfaces

[suthakar sundaralingam]

Hi Team,

I'm trying to setup a 5508 WLC from scratch. I have configured the device with basic configuration via CLI. 

The interface configuration is as follows,

WLC

1. Management interface: 10.100.10.21 / Gateway 10.100.10.254 (/24)

2. service port : 1.1.1.1/24

(Cisco Controller) >show interface summary

Number of Interfaces.......................... 5

Interface Name Port Vlan Id IP Address Type Ap Mgr Guest
-------------------------------- ---- -------- --------------- ------- ------ -----
management LAG 10 10.100.10.21 Static Yes No
redundancy-management LAG 10 0.0.0.0 Static No No
redundancy-port - untagged 0.0.0.0 Static No No
service-port N/A N/A 1.1.1.1 Static No No
virtual N/A N/A 10.100.20.1 Static No No

I'm trying to reach the WLC via following setup

1. My laptop (ip:10.100.10.254/24   gw:10.100.10.21) -----> WLC (service port) 

2. My laptop (10.100.10.254/24   gw: 10.100.10.21) -----> WLC (SFP/eithernet) 

3. My laptop (1.1.1.2/24   gw: 1.1.1.1) ----->  WLC (service port) 

4.My laptop (1.1.1.2/24   gw: 1.1.1.1) ----->  WLC (SFP/eithernet) 

I was only managed to ping the controller (both management interface/service port) with option/setup 3 (as above). 

Can someone explain me the logic behind this? My understanding is management should be reachable with option 1. How come i can ping management interface by directly connecting to service port? 

Regards,

Suthakar

You are tagging the traffic with VLAN 10 out of the management port. You need to set the interface to VLAN 0 to not tag the traffic.

We access the device using the management interface IP.. service port is like a life saver, it should be kept in different super net of management and AP manager.. so that if the management is not accessible.. we can control the device using service port.. the below link may help you..

To set up.. make the switchport connecting to thew WLC a trunk allowing all VLANS.. the config guide will help you out.. (the above link)
