Hello,
I m Shubhangi Sakpal, I am managing the LAN of Reliance Ind.
I am facing the problem with ethernet port. The specific port works on only 10mbps half duplex speed.
Can u guide me, how to get 100mbps speed on this specific port.

What is current setting on the port that you are having issue with. Also, can you post a copy of the "show run interface xxx", so we can see what is configured currently. Also, what is connected on the other end of the port.
Please refer the below URL for information on Speed/Duplex settings.

can you show us "sh run int fa4/0/12"?
what is the another equipment connected 3W_Cabin32`s f4/0/12?
if the another equipment is also cisco that is also 100M port,speed: auto, Duplex : auto
may be you need type a command below:
speed 100

hi,
ASFAIK that manual config of 100 Mbps @ full duplex do not interact properaly with interfaces configd with auto.This is because as per 802.3u standard both interfces recuire to send auto-negoatiation parameters for link only when both ends are confgd for auto-neg.If one end is hard coded then there will b duplex mismatch resulting errors and resulting switch interface to operate in half duplex.
As cisco recomondes always manually confgd 10/100-Mbps fastethernet & 10/100/1000Mbps gig ethernet on both link ends for critical connections to servers or 3rd party equipment.
Use auto-neg for interconnecting cisco devices and user workstations.Please check the other end settings and if possible do set the speed and duplex settings manually @ both ends.
HTH,
