Ethernet Switching

 

Monitoring Ethernet Switching

Purpose

Use the monitoring functionality to view the Ethernet switching page.

Action

To monitor Ethernet switching, select Monitor>Switching>Ethernet Switching in the J-Web user interface if you are using SRX5400, SRX5600, or SRX5800 platforms.

Or

Select Monitor>Ethernet Switching in the J-Web user interface.

Meaning

Table 74 summarizes key output fields in the Ethernet switching page.

Table 74: Ethernet Switching Monitoring Page

Field

Value

Additional Information

Ethernet Switching Table Information

VLAN

The VLAN for which Ethernet switching is enabled.

MAC Address

The MAC address associated with the VLAN. If a VLAN range has been configured for a VLAN, the output displays the MAC addresses for the entire series of VLANs that were created with that name.

Type

The type of MAC address. Values are:

  • static—The MAC address is manually created.

  • learn—The MAC address is learned dynamically from a packet's source MAC address.

  • flood—The MAC address is unknown and flooded to all members.

Age

The time remaining before the entry ages out and is removed from the Ethernet switching table.

Interfaces

Interface associated with learned MAC addresses or All-members (flood entry).

MAC Learning Log

VLAN-ID

Displays the VLAN ID.

MAC Address

Displays the learned MAC address.

Time

Displays timestamp when the MAC address was added or deleted from the log.

State

Indicates the MAC address learned on the interface.

Monitoring Spanning Tree

Purpose

Use the monitoring functionality to view the Spanning Tree page.

Action

To monitor spanning tree, select Monitor>Switching>Spanning Tree in the J-Web user interface.

Meaning

Table 75 summarizes key output fields in the spanning tree page.

Table 75: Spanning Tree Monitoring Page

Field

Value

Additional Information

Bridge parameters

Context ID

An internally generated identifier.

Enabled Protocol

Spanning tree protocol type enabled.

Root ID

Bridge ID of the elected spanning tree root bridge.

The bridge ID consists of a configurable bridge priority and the MAC address of the bridge.

Bridge ID

Locally configured bridge ID.

Inter instance ID

An internally generated instance identifier.

Extended system ID

Extended system generated instance identifier.

Maximum age

Maximum age of received bridge protocol data units (BPDUs).

Number of topology changes

Total number of STP topology changes detected since the switch last booted.

Forward delay

Spanning tree forward delay.

Interface List

Interface Name

Interface configured to participate in the STP instance.

Port ID

Logical interface identifier configured to participate in the STP instance.

Designated Port ID

Port ID of the designated port for the LAN segment to which the interface is attached.

Port Cost

Configured cost for the interface.

State

STP port state. Forwarding (FWD), blocking (BLK), listening, learning, or disabled.

Role

MSTP or RSTP port role. Designated (DESG), backup (BKUP), alternate (ALT), or root.

Monitoring IGMP Snooping

Purpose

Use the monitoring functionality to view the IGMP Snooping page.

Action

To display IGMP snooping details in the J-Web user interface, select Monitor>Switching>IGMP Snooping.

To display IGMP snooping details in the CLI, enter the following commands:

  • show igmp-snooping route

  • show igmp-snooping statistics

  • show igmp-snooping vlans

Meaning

Table 76 summarizes the IGMP snooping details displayed.

Interfaces

Indicates the interfaces configured as switching interfaces that are associated with the multicast router.

Groups

Indicates the number of the multicast groups learned by the VLAN.

MRouters

Specifies the multicast router.

Receivers

Specifies the multicast receiver.

IGMP Route Information

VLAN

The VLAN for which IGMP snooping is enabled.

Group

GVRP Status

Displays whether GVRP is enabled or disabled.

GVRP Timer

Displays the GVRP timer in millisecond.

Join

The number of milliseconds the interfaces must wait before sending VLAN advertisements.

Leave

The number of milliseconds an interface must wait after receiving a Leave message to remove the interface from the VLAN specified in the message.

Leave All

The interval in milliseconds at which Leave All messages are sent on interfaces. Leave All messages maintain current GVRP VLAN membership information in the network.
