Configure Bandwidth for a specific port?

[grip27grip28]

I have a Cisco router (3825) and switch (3750).  I have an end-user that needs more bandwidth allocated to him for a 2 hour window during the day.  I would like to allocate his port to use 60% of the bandwidth available during those 2 hours in order for him to perform his duty and then return things to normal after that 2 hour window.  

Can anyone please assist me with what commands to write on the router and switch (his particular port) to make this happen?

Also please note I have an ASA 5512 on my network as well, not sure if any configs need to be done for the ASA..

Any help or pointing me in the right direction would be appreciated.

thanks

Richard,

If it is a known two hour window during the day you will want to use a time-based ACL for a specific QoS policy for his IP address.  You could then apply it to an interface on the 3825.

Best regards,

Tim,

I am seeking the commands to place on my router and his switch port to make this happened.  The 2 hour window is not of great concern, but what commands do I implement?

Richard, 

On your 3825 assuming a 10 meg WAN(/internet) circuit:  You can apply the policy out to the WAN/internet as well, if you have bi-directional traffic.

This for Internet bandwidth? If so, I presume it's much less than your LAN bandwidth. If so, you can deal with egress bandwidth, on the 3825, along the lines Tim shows. Doing similar, for ingress bandwidth, is generally impractical on "ordinary" routers (and/or switches).

Hello,

on a side note, you could also use an EEM script with a cron timer. Just add the access list, class map and policy map, and use the EEM script to apply it to the interface. In the below sample, the policy is applied at 11, and removed at 13.

event manager applet BANDWIDTH_LIMIT_ON
event timer cron name BANDWIDTH_LIMIT_ON cron-entry "0 11 * * *" maxrun 9999999
action 1.0 cli command "enable"
action 1.1 cli command "conf t"
action 1.2 cli command "interface GigabitEthernet0/0"
action 1.3 cli command "service-policy output QOS_BANDWIDTH"
action 1.4 cli command "end"
action 1.5 cli command "wr mem"

event manager applet BANDWIDTH_LIMIT_OFF
event timer cron name BANDWIDTH_LIMIT_OFF cron-entry "0 13 * * *" maxrun 9999999
action 1.0 cli command "enable"
action 1.1 cli command "conf t"
action 1.2 cli command "interface GigabitEthernet0/0"
action 1.3 cli command "no service-policy output QOS_BANDWIDTH"
action 1.4 cli command "end"
action 1.5 cli command "wr mem"
