Configures the LLDP port to advertise or not advertise MED network policy TLVs. This TLV advertises This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches. configuration and associated Layer 2 and Layer 3 attributes that apply for a set of specific applications on that port. You can advertise up to 8 TLVs, each for a specific application, per port/VLAN. Each application type can exist only once per port. This TLV tells the endpoint the specific VLAN to use for the specific application, along with its unique priority.
all | Specifies all ports on the switch. |
port_list | Specifies one or more ports or slots and ports. |
advertise | Specifies to send the information to neighbors. |
no-advertise | Specifies not to send the information to neighbors. |
advertise | Specifies to send the information to neighbors. |
voice | Specifies voice application on specified port/VLAN(s). |
voice-signaling | Specifies voice signaling application on specified port/VLAN(s). |
guest-voice | Specifies guest voice application on specified port/VLAN(s). |
guest-voice-signaling | Specifies guest voice signaling application on specified port/VLAN(s). |
softphone-voice | Specifies soft phone voice application on specified port/VLAN(s). |
video-conferencing | Specifies videoconferencing application on specified port/VLAN(s). |
streaming-video | Specifies streaming video application on specified port/VLAN(s). |
video-signaling | Specifies video signaling application on specified port/VLAN(s). |
vlan_name | Specifies the VLAN the
specified application is using. NOTE: This parameter does not apply when the no-advertise parameter is configured. |
dscp_value | Specifies the DSCP value for
the specified application. This is a 6-bit value from 0 to 63. NOTE: This parameter does not apply when the no-advertise parameter is configured. |
priority-tagged | Use this if you want priority
tagging, and the VLAN is configured as untagged on the port. (The
endpoint sends out frames for the specified application with a tag
of 0.) NOTE: This parameter does not apply when the no-advertise parameter is configured. |
No advertise.
This command enables the LLDP MED network policy TLV, which allows network connectivity devices and endpoint devices to advertise VLAN configuration and associated Layer 2 and Layer 3 attributes that apply for a set of specific application on that port. This TLV can be enabled on a per port/VLAN basis. Each application type can exist only once on a port.
You can enable the transmission of a TLV policy for each application. A maximum of 8 TLVs can be enabled, and each can have a unique DSCP value and/or priority tagging.
You must configure the LLDP MED capabilities TLV before configuring this TLV. Configure the LLDP MED capabilities TLV using the configure lldp ports [all | port_list] [advertise | no-advertise] vendor-specific med capabilities command.
As with all the LLDP MED TLVs, the switch sends this TLV only after it detects a MED-capable device on the port. The switch does not automatically send this TLV after it is enabled; the switch must first detect a MED-capable device on the port.
Application type
Used as configured.
Unknown policy flag
Set to 0.
Tagged flag
Set to tagged for tagged VLANs; set to untagged for untagged VLANs. By default, set to 0.
VLAN ID
Copied from the VLAN. However, if you configure the priority-tagged parameter, this value is set to 0.
Layer 2 priority
Copied from the VLAN priority.
DSCP value
Uses the value configured in the dscp parameter.
Note
See the documentation provided by the manufacturer of connected devices regarding values.
The following command configures all ports to advertise videoconferencing on the VLAN video with a DSCP of 7 to neighbors:
configure lldp ports all advertise vendor-specific med policy application video-conferencing vlan video dscp 7
This command was first available in ExtremeXOS 11.5.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches.
