Yet another ADAC and LLDP Question
« on: January 17, 2014, 11:14:23 AM »
I am back to implementing Aastra 6757i VoIP phones in my infrastructure. I am using a 5520 with SW:v6.2.5.027.
I configured ADAC with LLDP and when I default the phone it goes through it's LLDP stage, then DHCP and picks up an IP from the Data VLAN??

Phones connected to ports 3, 5.
Config:

 *** VLAN ***

Your switch configuration looks correct concerning ADAC since the Voice_VLAN is being assigned to the ports with phones.

We use Polycom in my environments.  Polycom is very specific about which TLVs are required for it to accept Network Policy via LLDP.  Check the Aastra documentation to make sure you have all of the required TLVs in place.

Here's what works for me-

!
! *** 802.1ab ***
!

interface FastEthernet ALL
lldp tx-tlv port 1/ALL,2/ALL dot3 link-aggregation mac-phy-config-status maximum-frame-size mdi-power-support
lldp tx-tlv port 3/ALL,4/ALL dot3 link-aggregation mac-phy-config-status maximum-frame-size
lldp tx-tlv port 1/ALL,2/ALL med extendedPSE inventory med-capabilities network-policy
exit
!
! *** 802.1ab vendor-specific Avaya TLVs config ***
!
!
! *** 802.1AB MED Voice Network Policies ***
!
interface FastEthernet ALL
lldp med-network-policies port 1/ALL,2/ALL,3/ALL,4/ALL voice priority 6 tagging tagged vlan-id 1080
lldp med-network-policies port 1/ALL,2/ALL,3/ALL,4/ALL voice-signaling priority 6 tagging tagged vlan-id 1080


The stack this runs on is 4 units, the top two are 5520s and support PoE, the bottom two are 5510s and do not provide PoE.  That is why the settings are different for the top two and bottom two.

When I first started testing the Polycom phones in our environment it was very helpful to set up a port-mirror and watch the boot process with Wireshark. Filter on LLDP- by default the switch will not send the LLDP-MED information unless it detects the device as a MED capable endpoint.

Optionally, add the MAC range to the ADAC table and do ADAC-MAC and DHCP options instead.

ADAC is working properly- you can see it is adding the Voice_VLAN to the ports he has phones connected to.

Put the Voice VLAN into option 132.

TankII

************************

Using Option 132 (802.1P VLAN ID) and Option 43
to Transfer VLAN ID Assignment Using DHCP
There are now two ways of transporting the VLAN ID parameter in the Dynamic Host Configuration Protocol (DHCP):

By DHCP Option 43 (ven
dor specific information)

By DHCP Option 132 (802.1P VLAN ID)
When the phone receives the VLAN ID from the DHCP and the
value is different from the on
e used by the phone to trig-
ger the DHCP request, the phone reboots and then sends a new DHCP request in the new VLAN. The phone will remem-
ber the VLAN ID obtained by
DHCP options so that on a re
boot, the phone will send a DHCP request using the correct
VLAN.
If using DHCP Option 43 to transfer VLAN ID assignment the following sub-options are utilized. Additionally, the corre-
sponding rules must be followed:
Alternatively, administrators can use the
dhcp option 132 vlan id enabled
parameter to enable the VLAN ID assign-
ment transfer using DHCP feature. Option 132 provides the sa
me functionality as Option 43 but the data format of the
VLAN ID value must be 2 bytes, whereas the first and second
bytes encompass the VLAN ID (the valid range of the VLAN
ID being 1 - 4095).
Precedence

LLDP values should have precedence over the DHCP

DHCP values should have precedence over the configuration files

DHCP should have precedence over the Local values (configured by the Local MMI of the phone)

DHCP Option 43 should have precedence over DHCP Option 132

I felt like adding to this topic since I've had some issues with LLDP and Polycom SoundStation IP devices.

Set your System Name

From what I can tell the LLDP standard doesn't allow for a 0 length TLV, but if you do not set your system name but include sys-name tlv then the switch will send a 0 length system name which Polycom devices will discard as corrupt.

Set through Enterprise Device Manager: Edit->Chassis->Chassis->SysName

Set through Console Menu: System Characteristics->sysName

Set through Console CLI: conf t -> snmp-server name "YourHostName"

Also a note, not sure where it changed, but voice vlan setup is different now in version 6.3.2 that I am running than specified here: http:// blog. michaelfmcnamara. com/2007/10/nortel-ers-5520-pwr-switch/ <-I'm not allowed to post links yet, take out the space...
You need to setup the voice vlan first now, then assign in adac.  This is described in the admin guides for 6.3.

We just gone done working with Avaya and Polycom on a 1692 issue.  The 5520, when running ADAC, is set to discard unregistered frames.  The 56XX series, configured identically, on the same code, disabled this setting when ADAC is enabled.  Version 1.4.2.0 code phones would not show up in the ARP table of 5520's.  We had to either disable unregistered frames, or manually configure tagged Voice VLAN with untag PVID enabled to make them work. 
Avaya and Polycom released new code. 1.4.2.05 fixes it.
