5520 Vlan advice

[subnet11]

Hi All,

 I am planning to introduce VLAN ( Voice & Data )in my network, and need some advices. We have the following configuration :
-HP Gigabit Switch --- > (Servers and PBX BCM that are connected)
-Configuration PBX---->192.168.100.x /24
-Configuration Servers ---->192.168.200.x/24

From the Hp switch we have a cable running to the Second floor where a Nortel BES 1020 is installed. 24 ports are POE, so we connected our IP Phones and Wrkstations on the same drop cable.

Workstations ip's ( configured via WIndows DHCP )
IP : 192.168.200.x
SM : 255.255.255.0
DG : 192.168.200.6 ( Routes to the Internet )

Nortel IP Phone ( Static IPs )
IP : 192.168.100.x
SM : 255.255.255.0
 
We are currently replacing our cable infrastructure on the first floor ( will need 50 IP phones and 50 Workstations) , and for every workplace we are gonna place two drop boxes. 1 for the workstation ( 50 total) and 1 for the IP Phone(50 total). The second floor stays the same they will use the same infrastructure as described above( 1drop for VOICE and DATA)

I have the following new devices
- 2 ERS 5520 new POE/48Port switches
- 1 ERS 4548/48Port Switch.

Could somebody provide the possible solutions where both Voice and Data are seperated,
- but connecting from my workstation with IP (192.168.200.254) to PBX IP 
   (192.168.100.1) is possible
- Ip Phones 1200 series should be configured with via DHCP server of BCM
- BCM Should also be accessible via the Internet

Thanks in advance!

Regards,

Hi Guys,

Yesterday, I was reading and reading and reading the Nortel IP Telephony Deployment Technical Configuration Guide. They provide some possible configuration methods.
1. Automatic Provisioning Configuration
2. Adac Configuration - Mac Detection using ERS 5500 and using DHCP
3. Adac Configuration Example - LLDP Detection using ERS 2500
4. Adac Configuration Example - LLDP-MED using ERS 4500 and Nortel IP Phones via an SMLT core

I wont use this anymore :
- BCM Should also be accessible via the Internet
- Hp Procurve Switch

I will still have
- The Bes 1020 on the second floor

I was thinking to implement this with the second method ; Mac Detection using ERS 5500 and using DHCP
- In the implementation Guide drawing of this method I came across that there are 2 ERS8600 L3 Switches. There is and
IST link between those. There is also a SMLT link between the ERS8600 and the ERS5520. I went to Wiki site to check the definition of an IST connection : InterSwitch Trunk (IST) is one or more parallel point-to-point links (Link aggregation) that connect two switches together to create a single logical switch. So the IST act as a single switch. As I go futher the Deployment Guide shows you the exact steps to configure the ERS5520-1 L3 Switch. What I don't know is how the ERS8600 are configured.

With the following switches (2xERS5520 & 1 x4548GT), which method (1,2,3 or 4) would be the best.

Your advice appreciated.

Hi subnet11,

Since you have a number of different switches you might need to implement different solutions unless you're willing to replace all the switches with a standard (ie. 4548, 5520, etc).

If you are just working with 50 IP phone you might find it easier to manually configure them rather than trying to configure ADAC/LLDP-MED, DHCP VLAN assignment, TFTP/HTTP automatic provisioning, etc. You can use ADAC/LLDP-MED (with capable switches) to assign voice VLAN ID automatically to the IP phones. You can then use DHCP to assign the appropriate S1, S2 values and if you don't want to manually configure the Node and TN information you can use the automatic provision (INFO-BLOCK) feature.

Good Luck!
