Hi all ,
Is the delay and bandwidth parameters are configurable in the switch interface ?
Actually In one of the Fa interface the delay is showing as 100 , in another interface output delay is showing as 1000. Even bandwidth is showing 100000Kbit and one 10000.
Kindly suggest.
Thanks,
Regards,
Vijay

HI Vijay,
Delay:
It is related to interface speed . The interfaces are 10/100/1000 capable. Depending on the negotiated bandwidth the default delay changes. Switchport/routed port has no effect. If you leave them "auto negotiated" then essentially the delay negotiates to match the port speed as per the below:
1Gbps = 10usec
100Mbps = 100usec
10Mbps = 1000usec
*** Note: important to note that changing the "bandwidth" statement doesn't change the negotiated "delay". Only the "speed" will change delay... but please note that changing "speed" command is potentially network impacting. The "speed" command changes the literal interface capabilities for negotiating link speed, whereas changing "bandwidth" and "delay" changes an imaginary representation of link throughput capabilities.
