1)what is the meaning of delay in cisco router config
2)delay setting on interface, what does it mean?
3)Delay 10000000 ----  Will it add latency by 10Sec… for the traffic going / coming on that interface???

Answer
Hi MC

Many thanks for your question.

Here goes:

Setting Delay on Cisco Routers -

Higher-level protocols may use delay information to make operating decisions. For example, IGRP can use delay information to differentiate between a satellite link and a land link.


To set a delay value for an interface, use the delay interface subcommand. The full syntax of this command follows.

delay tens-of-microseconds
no delay (removes)

The argument tens-of-microseconds specifies the delay for an interface or network segment in tens of microseconds. Default delay values may be displayed with the EXEC command show interfaces. The no delay command restores the default.
Note: The delay subcommand sets an informational parameter only; you cannot adjust the actual delay of an interface with this subcommand.



----------------


Here's Cisco ref guide for delay:

delay

To set a delay value for an interface, use the delay interface configuration command. Use the no form of this command to restore the default delay value.

delay tens-of-microseconds
no delay
Syntax Description

tens-of-microseconds
  

Integer that specifies the delay in tens of microseconds for an interface or network segment.

Default

Default delay values may be displayed with the EXEC command show interfaces.
Command Mode

Interface configuration
Usage Guidelines

This command first appeared in Cisco IOS Release 10.0.
Example

The following example sets a 30,000-microsecond delay on serial interface 3:

interface serial 3
delay 30000
---------------

So to answer 1) The meaning of delay is to delay inbound traffic.
2) delay setting determines the amount of delay to impose
3) 100000 will add delay of 10secs. 10000000 will add delay of 1000 secs.
