On Monday I will be attempting to configure QoS on a SMC7904BRB2 router (owned by a client, offsite). I do not have access to this router for testing, so I have been doing some research on how to configure this so that I am ready on Monday.
I found the user manual online here: https://www.smc.com/files/AD/MN_SMC7904BRA2_BRB2_EU.pdf On page 4-59 it details the QoS settings. This is what I was thinking of setting the options to (5 users on the network with 5 phones, light internet usage): QoS Settings Enable or Disable QoS Module Function: Enable Diffserv Forwarding Groups (name, min bandwidth allocation, allow more): BE, 0%, true AF1x, 0%, true AF2x, 0%, true AF3x, 0%, true AF4x, 0%, true EF, 20%, true (I just picked this number out of the air - I don't have bandwidth speeds yet, but hope to get them before Monday so that I can come up with a better number) Traffic Mapping Add traffic class with the following: Rule Name: VoIP Traffic Type: ? (the manual shows a drop down with "Any" selected and and "ADVANCED CONFIG" button - no further details are given) Map to Forwarding Group: EF Remark DSCP as: EF (101110) (again, this is a drop down with no further description about the options other than "the first 6 bits of the IP TOS field", which I'm guessing will be 101110) Direct to VC: By Routing? (this is also a drop down - I do not know what the other options are - I will have to review the current ATM PVC settings to see if there are multiple VCs - I think there's only 1, but I'm just guessing) Do these settings look OK? Should I add any other rules? I think I read somewhere that ACKs should be prioritized higher as well.
