HPE 5400 zl Switch Series - Logging Errors 00828 lldp: PVID Mismatch on Port

Issue

The logging buffer reports recurring informational messages similar to the ones given below :


I 06/09/12 14:17:16 00828 lldp: PVID mismatch on port L1(VID 1)with peer device
port 265(VID unknown)(1)

I 06/09/12 09:11:53 00828 lldp: PVID mismatch on port L1(VID r
device port 265(VID 1)(1)

Solution

The Port VLAN ID (PVID) is one of the optional TLVs (Type, Length, Value) carried in LLDP frames as part of the protocol operations. The PVID for a given port indicates the VLAN ID that will be associated with an untagged data frame received on the port.

In the following example, switch Rack2sw1 has been intentionally misconfigured to recreate the error. Rack2sw1 does not have an untagged Vlan configured for port L1.

The configuration, verification, and testing associated with the diagram follows:

Vlan Configuration:




Rack2sw1# show running-config vlan

Running configuration:

vlan 1
name "DEFAULT_VLAN"
tagged GDP,GUP,HDP,HUP
no untagged L1 <-----
untagged A1-A24,B1-B24,C1-C24,D1-D24,F1-F24,J1-J4,K1-K4,L2-L4
ip address 192.168.2.1 255.255.255.0

vlan 12
name "VLAN12"
tagged L1
ip address 192.168.12.1 255.255.255.0

Rack2sw2# show running-config vlan

Running configuration:

vlan 1
name "DEFAULT_VLAN"
untagged A1-A24,B1-B24,C1-C24,D1-D24,E1-E2,G1-G24,H1-H2,J1-J4,K1-K4,L1-L4
ip address 192.168.2.2 255.255.255.0

vlan 12
name "VLAN12"
tagged L1
ip address 192.168.12.2 255.255.255.0



Vlan Verification:



Rack2sw1# show vlans ports l1 detail

Status and Counters - VLAN Information - for ports L1

VLAN ID Name | Status Voice Jumbo Mode
------- -------------------- + ---------- ----- ----- --------

Rack2sw2# show vlans ports l1 detail

Status and Counters - VLAN Information - for ports L1

VLAN ID Name | Status Voice Jumbo Mode
------- -------------------- + ---------- ----- ----- --------

12 VLAN12 | Port-based No No Tagged



Configuration change/verification:



Rack2sw1(config)# vlan 1 untagged l1

Rack2sw1# show vlans ports l1 detail

Status and Counters - VLAN Information - for ports L1

VLAN ID Name | Status Voice Jumbo Mode
------- -------------------- + ---------- ----- ----- --------

Testing:



Rack2sw1# ping 192.168.2.2
192.168.2.2 is alive, time = 2 ms
Rack2sw1# ping 192.168.12.2
192.168.12.2 is alive, time = 1 ms
