l2 ping vlan
Trigger a Layer 2 ping, which acts like a native ping. Enable Connectivity Fault Management
(CFM) to debug Layer 2. It can also help you debug ARP problems by providing the ability to
troubleshoot next hop ARP records.

Command Parameters
- <1-4059>
-
Specifies the
VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to
4059 are configurable and the system reserves VLAN IDs 4060 to
4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if
you enable these flags, the system also reserves VLAN IDs 3500
to 3998. VLAN ID 1 is the default VLAN and you cannot create or
delete VLAN ID 1.
- burst-count <1-200>
- Specifies the burst count.
- data-tlv-size <0-400>
- Specifies the data
Type-Length-Value (TLV) size. The default is 0.
- frame-size <64-1500>
- Specifies the frame size. The
default is 0.
- mac <0x00:0x00:0x00:0x00:0x00:0x00>
- Specifies the MAC address.
- priority <0-7>
- Specifies the priority. The
default is 7.
- routernodename WORD<0-255>
- Specifies the router node
name.
- testfill-pattern all-zero
- Specifies the testfill pattern.
Range is: all-zero: null signal without cyclic redundancy check; all-zero-crc:
null signal with cyclic redundancy check with 32-bit polynomial;
pseudo-random-bit-sequence: PRBS without cyclic redundancy check; or
pseudo-random-bit-sequence-crc: PBRS with cyclic redundancy check with 32-bit
polynomial. A cyclic redundancy check is a code that detects errors. The default
is all-zero.
- testfill-pattern all-zero-crc
- Specifies the testfill pattern.
Range is: all-zero: null signal without cyclic redundancy check; all-zero-crc:
null signal with cyclic redundancy check with 32-bit polynomial;
pseudo-random-bit-sequence: PRBS without cyclic redundancy check; or
pseudo-random-bit-sequence-crc: PBRS with cyclic redundancy check with 32-bit
polynomial. A cyclic redundancy check is a code that detects errors. The default
is all-zero.
- testfill-pattern pseudo-random-bit-sequence
- Specifies the testfill pattern.
Range is: all-zero: null signal without cyclic redundancy check; all-zero-crc:
null signal with cyclic redundancy check with 32-bit polynomial;
pseudo-random-bit-sequence: PRBS without cyclic redundancy check; or
pseudo-random-bit-sequence-crc: PBRS with cyclic redundancy check with 32-bit
polynomial. A cyclic redundancy check is a code that detects errors. The default
is all-zero.
- testfill-pattern pseudo-random-bit-sequence-crc
- Specifies the testfill pattern.
Range is: all-zero: null signal without cyclic redundancy check; all-zero-crc:
null signal with cyclic redundancy check with 32-bit polynomial;
pseudo-random-bit-sequence: PRBS without cyclic redundancy check; or
pseudo-random-bit-sequence-crc: PBRS with cyclic redundancy check with 32-bit
polynomial. A cyclic redundancy check is a code that detects errors. The default
is all-zero.
- time-out <1-10>
- Specifies the interval in seconds.
The default is 3.
