MAPD 100MB ??

[tcomprojmgr]

Does anyone know of a way to configure the TN801B MAPD board to run at the 100/full network speed? I have heard from a contact in the industry that there are MAPD boards out there that have been "tweaked" to do so. Any information / news on this??

All of the MAP-Ds that I have are configured as 10/half.

yeah, everything that I've heard from Avaya "officially" is that this is not possible...but I just was wondering about other options....

are you finding bottlenecks at 10/half? cti traffic is pretty small -- in my call center with 300 agents, I rarely see any traffic over 1400 bps (15% of the 10 mb bandwidth).

 

[tcomprojmgr]

At first, there were a ton of bottlenecks because we weren't running the CTI traffic on an isolated sub-net, and the 10/half traffic was just getting killed. We have moved it to an isolated sub-net, but it is still vulnerable to a network storm at the hub....

We have about 1,200 CTI agents and the data volume is quite a bit. Any opportunity to up the speed to 100/full would be beneficial.

I wouldn't mind knowing how to change it to 100/full so that it would match everything else in the enterprise ... I dislike exceptions to the standard.

tcomprojmgr,

there is no way to set the map-d to 100/full, its nic is quite old and supports only 10/half.
the way to increase cti throughput is to use co-resident dlg on r12 or application enablement services on r13. the latter allows more than one link to the switch, for redundancy and load balancing.

Thanks dwalin -

Yeah, I was aware of the advances with r12+ ... unfortunately my company is putting off the upgrade until later...so I was looking for any possible solutions for r10/r11.

Have you considered a VLAN between your CTI Server and your MAPD.

Or better yet, install a second NIC in your CTI Server and connect the second nic to the MAPD w/ a cross-over cable. This will isolate network traffic for that segment.

 

[tcomprojmgr]

We are running on an isolated subnet (VLAN) for that segment, but even still...it is vulnerable to network storms at the Hub, right?

 

[SignalCorpNCO]

Did you say HUB? With HUB's, all ports associated with it share the same collision domain.

So if you have other devices that are not related to the CTI/ MAPD network hooked up to the hub, those devices could very well be flooding the hubs collision domain w/ garbage i.e. uni, multi and or other broadcast packets.

I had the same exact problem and ended up going w/ a second NIC on the CTI server and connected it to the MAPD w/ a cross-over cable because my employer would not drop the coin for a ethernet switch.
