Ning, In reply to your questions... 1) is CDP enabled on your switch port gi0/4? Yes. 2) can you enable both LLDP and CDP on gi0/4 and then check phone's behavior? The original problem I explained was when both CDP and LLDP were running on the port. 2) can you capture a wireshark trace on switch or on phone? I can, but I'm not in a position to do this right now. Navin, thanks, I'll look forward to hearing what they say. Do you need any other information from me? I'm going to be away from the office for the next week so my replies may be slow from tonight. I've also noticed a typo in my original post - we're using 8.6.3 not 8.6.4 as I originally suggested. ... View more

The switch is configured with auto voice VLAN enabled, with a VLAN ID of 2. Running config is shown below. The 3905 handset is connected on port 4 where LLDP is set to receive only. Any other handset in this port works fine with LLDP set to Tx and Rx. config-file-header switch0da7e6 v1.2.5.70 / R750_NIK_1_2_584_002 CLI v1.0 file SSD indicator encrypted @ ssd-control-start ssd config ssd file passphrase control unrestricted no ssd file integrity control ssd-control-end cb0a3fdb1f3a1af4e4430033719968c0 ! spanning-tree priority 4096 vlan database vlan 2-5,100 exit voice vlan id 2 voice vlan oui-table add 0001e3 Siemens_AG_phone________ voice vlan oui-table add 00036b Cisco_phone_____________ voice vlan oui-table add 00096e Avaya___________________ voice vlan oui-table add 000fe2 H3C_Aolynk______________ voice vlan oui-table add 0060b9 Philips_and_NEC_AG_phone voice vlan oui-table add 00d01e Pingtel_phone___________ voice vlan oui-table add 00e075 Polycom/Veritel_phone___ voice vlan oui-table add 00e0bb 3Com_phone______________ bonjour interface range vlan 1 ip access-list extended ACL01 permit tcp 192.168.2.249 0.0.0.0 any 192.168.0.252 0.0.7.0 www deny tcp 192.168.2.0 0.0.0.255 any 192.168.0.252 0.0.7.0 www permit ip any any exit hostname switch0da7e6 management access-list SecureAccess permit ip-source 192.168.1.0 mask 255.255.255.240 permit ip-source 192.168.2.0 mask 255.255.255.240 permit ip-source 192.168.3.0 mask 255.255.255.240 permit ip-source 10.1.1.0 mask 255.255.255.240 exit management access-class SecureAccess passwords aging 0 ip ssh server ! interface vlan 1 ip address 192.168.1.252 255.255.255.0 no ip address dhcp ! interface vlan 2 name BE3000 ip address 192.168.2.252 255.255.255.0 ! interface vlan 3 name UC320 ip address 192.168.3.252 255.255.255.0 ! interface vlan 4 name UC540BRI ip address 192.168.4.252 255.255.255.0 ! interface vlan 5 name UC540FXO ip address 192.168.5.252 255.255.255.0 ! interface vlan 100 name UC320Phones ip address 10.1.1.252 255.255.255.0 ! interface gigabitethernet2 switchport trunk native vlan 2 ! interface gigabitethernet3 switchport trunk allowed vlan add 100 switchport trunk native vlan 3 no macro auto smartport ! interface gigabitethernet4 storm-control broadcast enable storm-control broadcast level 10 storm-control include-multicast port security max 10 port security mode max-addresses port security discard trap 60 spanning-tree portfast switchport trunk allowed vlan add 2 no lldp transmit macro description ip_phone_desktop !next command is internal. macro auto smartport dynamic_type ip_phone_desktop ! interface gigabitethernet5 storm-control broadcast enable storm-control broadcast level 10 storm-control include-multicast port security max 10 port security mode max-addresses port security discard trap 60 spanning-tree portfast switchport trunk allowed vlan add 2 macro description ip_phone_desktop !next command is internal. macro auto smartport dynamic_type ip_phone_desktop ! interface gigabitethernet6 storm-control broadcast enable storm-control broadcast level 10 storm-control include-multicast port security max 10 port security mode max-addresses port security discard trap 60 spanning-tree portfast switchport trunk allowed vlan add 2 macro description ip_phone_desktop !next command is internal. macro auto smartport dynamic_type ip_phone_desktop ! interface gigabitethernet11 switchport trunk native vlan 100 no cdp enable no macro auto smartport ! interface gigabitethernet12 switchport trunk native vlan 100 no cdp enable no macro auto smartport ! interface gigabitethernet16 storm-control broadcast enable storm-control broadcast level 10 storm-control include-multicast port security max 10 port security mode max-addresses port security discard trap 60 spanning-tree portfast switchport trunk allowed vlan add 2 macro description ip_phone_desktop !next command is internal. macro auto smartport dynamic_type ip_phone_desktop ! interface gigabitethernet17 storm-control broadcast enable storm-control broadcast level 10 storm-control include-multicast port security max 10 port security mode max-addresses port security discard trap 60 spanning-tree portfast switchport trunk allowed vlan add 2 macro description ip_phone_desktop !next command is internal. macro auto smartport dynamic_type ip_phone_desktop ! interface gigabitethernet23 switchport trunk native vlan 100 no cdp enable no macro auto smartport ! interface gigabitethernet24 switchport trunk native vlan 100 no cdp enable no macro auto smartport ! interface gigabitethernet27 channel-group 1 mode auto ! interface gigabitethernet28 channel-group 1 mode auto ! interface Port-channel1 speed 1000 ! ...

Hi Sanjay, I've checked the switch and LLDP-MED is enabled on all of the ports. Thanks. ... View more

I have some further information.. If I enable LLDP on the switch port that connects to the 3905 the handset shows VLAN 4095 in the Operational VLAN ID, my Admin VLAN ID setting is ignored and the handset will not connect on the tagged VLAN 2 port. If I configure the switch port onto VLAN 2 (untagged) the phone connects, which suggests the handset is not tagging its traffic. If I disable LLDP on the switch port that connects to the 3905 and set it to VLAN 2 (tagged) the handset will use the Admin VLAN ID which I've configured as 2 and it will connect to the system. Interestingly, in this setup the handset shows Operational VLAN ID 2, but this may simply be because it has taken my Admin VLAN ID setting. I should have mentioned as well, the phones I am testing with all have static IP addresses so I have no DHCP to worry about in these tests. I've also obtained logs from the handset's web management pages, the parts that appear relevant are below: With LLDP activated on the switch port: 16:31:13:871 x [SW] switchConf_confVlan(), type: 1, voice: 4095, native: 1 16:31:13:872 x [SW] swConfVlan(), nVoiceVID: 4095, nNativeVID: 1, Freezed: 0 16:31:13:903 x [SW] swConfVlan(), No Voice Vlan 16:31:13:905 x [SW] switchConf_confVlan(), SW_VLAN_OPERA_TYPE_LLDPCDP 16:31:13:905 x [CENTRAL] State transit REGISTERING --> CONFIGURING_IP 16:31:13:906 x [CENTRAL] Begin to config ip 16:31:13:923 x [CENTRAL] IP Address = 192.168.2.200 16:31:13:924 x [CENTRAL] Netmask    = 255.255.255.0 16:31:13:924 x [CENTRAL] Gateway    = 192.168.2.252 With LLDP deactivated on the switch port: 16:33:39:571 x [SW] switchConf_confVlan(), type: 1, voice: 2, native: 1 16:33:39:572 x [SW] swConfVlan(), nVoiceVID: 2, nNativeVID: 1, Freezed: 0 16:33:39:661 x [SW] switchConf_confVlan(), SW_VLAN_OPERA_TYPE_LLDPCDP 16:33:39:662 x [CENTRAL] State transit REGISTERING --> CONFIGURING_IP 16:33:39:663 x [CENTRAL] Begin to config ip 16:33:39:680 x [CENTRAL] IP Address = 192.168.2.200 16:33:39:680 x [CENTRAL] Netmask    = 255.255.255.0 16:33:39:681 x [CENTRAL] Gateway    = 192.168.2.252 ...

Hi Sanjay, I've tried this on one machine and it hasn't made a difference. On that PC, when you double click the installer icon you get the UAC box popup but when you click 'yes' to allow permission nothing happens - no installer, no errors, no process running in task manager. I haven't tried it on my PC yet but I will try to at some point today and come back to you. Thank you for your help so far. ... View more

Hi Navin, I get the error about 3 seconds after the installer starts, so right at the very beginning before anything has installed. Craig ... View more
