Change WLC 5508 port speed

Sun, 04 Jul 2021 06:17:09 GMT

I connect a copper SFP on port 2 of WLC 5508 to a ASA 5510 firewall. The links between two devices are down. Since ASA 5510 only support 100 full, how do I change port speed on port 2 to 100.

Thanks

You can't. The WLC is 1000 full duplex only.

Put a gigabit switch inbetween the WLC and the ASA and that should fix your issue.

Does this mean, I couldn't change port speed on the WLC? Why do I need to buy another Gigbit switch for 2 connection?

what is the design that requires you to go directly to the ASA? If it's for guest, you could L2 segregate and ACL the heck out of it. That way you can use a switch you already have

HTH,

No you can't.

Look at the module you put in the WLC... They are GLC-T... Gigabit only. The WLC's from the 4400's to the 5508's have always been gigabit only as it mentions in the data sheet and the configuration guides. So if your ASA doesn't support gigabit, then yes you will need to invest in a switch or an ASA with gigabit Ethernet ports.

Scott and Steve are on target with their comments. The 5508 is gig only.

Yes you can. You can change the speed setting to GIGABIT, nothing less.

Why do I need to buy another Gigbit switch for 2 connection?

What do you mean by "another"???? Do you have an existing GigabitEthernet switch that you can connect the WLC into?

You need a GigabitEthernet port to connect the WLC's GigabitEthernet port. And then you can have a FastEthernet port to connect the SAME SWITCH to your ASA.

WLC --- (1000BaseTx) --- Switch --- (10/100BaseTx) --- ASA

Does this make sense to you?

I agree with Scott that gigabit speed is not changeable and with Steve that a vlan should eliminate extra switch.

Thanks everyone's input
