Switching

New Monitor pages for enhanced switching allow you to monitor the information and status about the following:

Monitoring Ethernet Switching

To view information about the Ethernet Switching interface details, select Monitor>Switching>Ethernet Switching in the J-Web interface, or enter the following CLI command:

Table 171 summarizes the Ethernet Switching output fields.

Table 171: Summary of Ethernet Switching Output Fields

Field

Values

Additional 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).

 

VLAN-ID

The VLAN ID.

 

MAC Address

The learned MAC address.

 

Time

Timestamp when the MAC address was added or deleted from the log.

 

State

Indicates the MAC address learned on the interface.

 

Monitoring Spanning Tree

To view status and information about the spanning tree interface parameters, select Monitor>Switching>Spanning Tree in the J-Web interface or enter the following CLI commands:

Table 172 summarizes the Spanning Tree output fields.

Table 172: Summary of Spanning Tree Output Fields

Field

Values

Additional Information

Spanning Tree 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.

 

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.

 
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

To view information about the IGMP snooping parameters, select Monitor>Switching>IGMP-Snooping in the J-Web interface, or enter the following CLI commands:

Table 173 summarizes the IGMP Snooping output fields.

Table 173: Summary of IGMP Snooping Output Fields

Field

Values

Additional Information

VLAN

The VLAN for which IGMP snooping is enabled.

 

Interfaces

Indicates the number of interfaces in the VLAN.

 

Groups

Indicates the multicast groups learned by the VLAN.

 

MRouters

Indicates the MRouters learned by the VLAN.

 

Receivers

Specifies the multicast receiver.

 

Group

Indicates the multicast groups learned by the VLAN.

 

Next-Hop

The next hop assigned by the switch after performing the route lookup.

 

Monitoring GVRP

To view information about global GVRP configuration, select Monitor>Switching>GVRP in the J-Web interface or enter the following CLI command:

show gvrp

Table 174 summarizes the GVRP output fields.

Table 174: Summary of GVRP Output Fields

Field

Values

Additional Information

GVRP

Global GVRP Configuration

List of global GVRP configuration statistics such as:

  • GVRP status—Displays whether GVRP is enabled or disabled.
  • 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.
 

Interfaces

List of interface-based configuration statistics:

  • Interface Name—The interface on which GVRP is configured.
  • Protocol Status—Displays whether GVRP is enabled or disabled.
