2526T to 3526GT questions
« on: March 21, 2017, 10:43:46 AM »
Hi there !

We're going to change our 2526T soon and I was wondering if it's possible to :
- restore a backup file from a 2526T on a new 3526GT (not sure that will work :/)
- or paste an ascii backup of a 2526T on a new 3526GT (other than making sure that the port numbers match, are there any other points to be aware of ?)

Another question (not completely 3500ERS related), do any of you use the dhcp server feature on the switchs ? Does it work the same way as any other dhcp server (like making reservations) ? We've got a remote site and might need to install a dhcp server there...

Cheers !

Hi shehzaad,

welcome to the forums.
Sure, you can "import" the ASCII config file from old 2500 series into the 3500/3600 series, except any configuration related to QoS, if exists.

None of my clients are using the "internal" DHCP server, but in some cases it'd make sense.

I tried to define an host declaration:
ena
conf t
ip  dhcp-server pool test host 10.10.10.10 aa.bb.cc.dd.ee.ff option-1 255.255.255.0 option-3 10.10.10.1

Possible values are:
  host        Static IP allocation
  lease       Pool's lease time
  option-1    Configure client's subnetmask
  option-120  Configure list of SIP servers
  option-150  Configure list of TFTP servers
  option-176  Configure Avaya IP phones' option-176 parameters
  option-241  Configure Avaya IP phones' option-241 parameters
  option-242  Configure Avaya IP phones' option-242 parameters
  option-3    Configure list of routers
  option-6    Configure DNS servers
  option-60   Vendor class identifier option
  range       Dynamic IP address allocation

Good luck

Thanks for the quick answer !

I'll give the ascii config a try then. Got 18 of them to change. Haven't got QOS on any of them.

Will give it a try too with the dhcp server. I'll build a lab and see how things go with the Web client.

2 more questions regarding the dhcp server :
- is option-3 is the gateway ?
- host ip = switch IP ?

Cheers

- is option-3 is the gateway ? <= Yes
- host ip = switch IP ? <= No, the IP of the client there you define the reservation

We currently have ERS 2526's operating as DHCP servers at 2 remote sites.  They provide IP addresses for the IP phones at those sites.  Never had any problems with that setup.

One thing I never figured out was how to program a scope that is not in the Management VLAN.  So right now the switches Mgmt VLAN is the same as the Voice VLAN.  Not ideal, but it works and I'm happy.   ;D
