Monitoring Enhanced 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:

show ethernet-switching table
show ethernet-switching mac-learning-log

Table 86 summarizes the Ethernet Switching output fields.

Table 86: 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:

show spanning-tree interface
show spanning-tree bridge

Table 87 summarizes the Spanning Tree output fields.

Table 87: 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:

show igmp-snooping vlans
show igmp-snooping route

Table 88 summarizes the IGMP Snooping output fields.

Table 88: 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 89 summarizes the GVRP output fields.

Table 89: 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.

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.
