Output Fields

Table 1 lists the output fields for the show fip snooping command. Output fields are listed in the approximate order in which they appear.

Table 1: show fip snooping Output Fields

Field Name

Field Description

Level of Output

VLAN

Name of the VLAN.

All

Mode

(QFX Series only)

Snooping mode enabled on the FCoE VLAN:

  • VN2VF Snooping—The FCoE VLAN is configured for FIP snooping between an ENode VN_Port and a switch VF_Port.

  • VN2VN Snooping—The FCoE VLAN is configured for VN_Port to VN_Port FIP snooping between ENode VN_Ports.

All

FC-MAP

FCoE mapped address prefix of the FCoE forwarder for the VLAN.

All

FCF or FCF-MAC

MAC address of the FCF.

All

Session Count or Active Sessions

Current number of virtual link sessions with VN_Ports.

All

VN_Port Count

(QFX Series only)

Number of VN_Ports active on an ENode.

brief

Configured FKA-ADV

FIP keepalive interval in seconds configured on the FCF multiplied by three. For example, if the FKA_ADV period configured on the FCF is 86 seconds, the value of this field is 258.

For the QFX Series only, the output of this field is always 0 (zero) if the VLAN is an FCoE-FC gateway VLAN. If the VLAN is a FIP snooping VLAN (a transit switch VLAN), then the output is accurate. This is because for an FCoE-FC gateway VLAN, FIP snooping is performed internally and the keepalive advertisements are not tracked by the switch’s Ethernet module.

detail

Running FKA-ADV

Runtime interval in seconds of the last FIP keepalive advertisement the FCF received. This value changes every time the FCF receives an FKA_ADV.

For the QFX Series only, the output of this field is always 0 (zero) if the VLAN is an FCoE-FC gateway VLAN. If the VLAN is a FIP snooping VLAN (a transit switch VLAN), then the output is accurate. This is because for an FCoE-FC gateway VLAN, FIP snooping is performed internally and the keepalive advertisements are not tracked by the switch’s Ethernet module.

detail

Beacon Period

(QFX Series only)

Beacon period interval in milliseconds.

detail

VN2VN Mode

(QFX Series only)

Mode of VN2VN_Port snooping:

  • Multi-Point—Multiple ENodes are connected to the network and form multiple virtual links. Each virtual link is created between one pair of VN_Ports. This is analogous to the loop mode in traditional FC networks.

  • Point-to-Point—Two ENodes are connected to the network and form a single VN_Port to VN_Port virtual link. This is analogous to the point-to-point FC link between an FC initiator and an FC target.

detail

ENode-MAC

MAC address of the connected FCoE node (ENode).

All

Interface

Interface connected to the ENode.

(QFabric System or Junos Fusion satellite command output only)

When an FCoE LAG has been configured, this field displays both the LAG interface and the LAG member interface connected to the ENode.

detail

VN-Port MAC

MAC address of a VN_Port on the ENode.

All

FKA-ADV

Runtime interval in seconds of the last FIP keepalive advertisement the ENode sent to the FCF on behalf of the VN_Port (VN_Port FKA_ADV). This value changes every time the ENode sends a VN_Port FKA_ADV to the FCF.

detail

Active VN_Ports

(QFX Series only)

Number of VN_Ports active on an ENode.

detail

Vlink far-end VN-Port-MAC

(QFX Series only)

Media access control (MAC) address of the VN_Port at the other end of the virtual link.
