OK folks, I found the issue! Apologies to Nortel for accusing their dodgey code :-P DaddyOfThree, The penny dropped when you mentioned that it sounded like a DOS attack on port 23. I remembered that last month we had some evaluation network monitoring software in a virtualised environment...

99.999% sure, I mentioned there is no firewall between the PC and the stack in my first post and that includes host based firewalls - we don't use them, only macafee but not relevant here. Also I can always telnet to the 4526T-pwr stacks we've recently installed over the MPLS and I built a new...

Thanks for the response. RADIUS was not used when we were on a managed services contract either. I spoke to the 3rd line guy I used to deal with and he used to login to each switch remotely via telnet and change the password in the console/configuration menu, which is how I done it also. The...

Very strange issue here that's got me scratching my head big time. Not service affecting, more of an annoyance! Background: 2 years in this job, always been able to access Passport core switches x 2 via telnet and device manager and been able to access 35 switch stacks which are accessible...

Hi DaddyOfThree, Yeah I probably should have put that in. We have dual separate WAN links with WAN routers (Cisco 2800's) which perform doy1q trunking. The voice and data sub interfaces on the router, IP addresses are .2 primary router, .3 backup router and we use .1 for the HSRP running...

Hi, We re-allocated a stack of 3 baystack 470pwr switches from a site that was closing down and just changed the IP address and default gateway etc to match the new site. We have a data, voice and mgmt VLAN configured on the switch stack and when we plugged the switch in I was unable to ping...

edkender We definitely will! Thanks for the help guys, have a good weekend.

oh yeah.... ELAN which is connected to a baystack switch and TLAN connected to separate Baystack switch.

Not sure what other information you require. I'll list everything maybe easier as the posts are becoming a bit scrambled; - CS1000E v4.5 software platform - Separate 1100 Sig server - may be 2 of hese for HA - MG1000E - MG1000T - SSC Cards - PIV processors in both cabinets connected together...

for the record I had a similar issue a while back before we swapped all of our phase 1 phones out. I had a phase 1 phone operating in a single Baystack 460pwr switch along with a mix of phase 1 & 2 i2002's & i2004's We added a Nortel Baystack 470pwr 24 port and configured as a stack. If you...

what type of phone is it? i2002/2004/1120E/1140E phase 1 or 2? etc etc

sorry meant cppm not sppm in previous post

tnphoneman yes that's correct edkender are you sure the ssc's would need replaced with sppm boards? I found this upgrade path presentation from Bell Canada which says to me we would only need to upgrade the sig servers to 1GB RAM. This document is quoted as upgrading to v5 as opposed to...

MagnaRGP Thanks so much, makes sense & I understand. I will check that out tomorrow re the fiber cards. Cheers Malc

just another question on this. Looking a bit further into the upgrade documentation, is the CP PM required as well as the PIV? Do these do completely separate things? The upgrade document I'm referring to is confusing as to wether you need both the PIV and CPPM or it's either or. Thanks...

MagnaRGP not sure if there are any fiber intergroup connections, all I know is the MG's connect via RJ45 from the card to the ELAN/TLAN....is this what you meant? Where/how do I check this out? tnphoneman, I'll get the part number of the processors tomorrow if possible without removing them...

Thanks edkender, why do you think we were told we needed to upgrade then? This has been prohibitive to us carrying out the upgrade in 2008 due to not having the budget to upgrade the processors. I was working on WAN/LAN data projects the last year and only just got involved in this side of...

Hi All, I'm fairly new to Nortel CS1000E admin / hardware so go easy on me! We are running a CS1000E v4.5 and are looking to plan upgrading to the 5.5 platform. We were advised that we would need to "upgrade our processors" for v5.5 to work. From reading Nortel documentation it seems to me...

There is a limitation on CS1000 v4.5 for NTP. This is fixed in 5.0 and above I believe.
