I have 3945 router with a Gig interface having an optical module(GLC-LC-SM).
Basically I use a fiber from my gig interface to ISP
My ISP doesnot allow the use of speed as auto/auto
But in my Gig interface, I want to stop autonegotiation.
I have a universal image 15.0(1)M3 -c3900-universalk9-mz.SPA.150-1.M3 with ipbasek9 and datak9 licences enabled
I dont have a command that disables speed negotiation
1) I have a doubt. Does speed 10(or) 100 (or) 1000 as mentioned below will disable negotiation.
Because in other IOS we have a seperate command "speed no-negotiate" that disables and we also
do a "speed <val>" to hardcode the speed
Router(config-if)#speed ?
10 Force 10 Mbps operation
100 Force 100 Mbps operation
1000 Force 1000 Mbps operation
auto Enable AUTO speed configuration
Please help on whether we need a seperate command to disable speed autonegotiation (or) will the speed <val>
do it ( manually configures a speed by disabling speed negotiation)
If so what is the use of speed no-negotiate that comes in certain IOS?
Thank you all.
