RAY RSL2-A-24X AGGREGATION SWITCH SPEED/DUPLEX CONFIGURATION:

RAY RSL2-A-24X AGGREGATION SWITCH image:

The Ray RSL2-A-24X is  Layer 3 Aggregation layer Cloud-managed 24 Port Full fiber switch with 24 (10 Gbe SFP+) and 2 (40 Gbe QSFP+) UPlink ports.

By default the Ray RSL2-A-24X switch has its switch port interfaces configured with speed and duplex set at Force 10G- Full duplex.  

Due to this default setting on the Ray RSL2-A-24X, when another Access Layer (L2+) Switch connects from its uplinks usually 1G SFP to the Ray RSL2-A-24X switch ports which have default speed and duplex of 10G SFP+, A speed and duplex mismatch error occurs and the port's link doesn't come up.

SOLUTION TO SPEED AND DUPLEX MISMATCH AND SWITCH PORT LINK STATUS DOWN ON RAY RSL2-A-24X SWITCH:

The following resolution steps and commands are to be configured on the Ray RSL2-A-24X  switch.

 Ray RSL2-A-24X#

 Ray RSL2-A-24X# config t

 Ray RSL2-A-24X(Config)#

Ray RSL2-A-24X(Config)# interface ethernet 1/0/1-24 

Ray RSL2-A-24X(Config-if-port-range)#

Ray RSL2-A-24X(Config-if-port-range)# speed-duplex force1g-full 

Ray RSL2-A-24X(Config-if-port-range)# 

Ray RSL2-A-24X(Config-if-port-range)# end

 Ray RSL2-A-24X#

 Ray RSL2-A-24X# copy running-config startup-config

important info!

int ethernet 1/0/1-24 : this command enters the switch port interface configuration range of ethernet port 1/0/1-24 

speed-duplex force1g-full : This command statically configures the Ray RSL2-A-24X speed and duplex from default Force10g-full to force1g-full
