Job aid

The following sections describe the fields in the outputs for the global IS-IS show commands.

show isis

The following table describes the fields in the output for the show isis command.


Parameter	Description
AdminState	Indicates the administrative state of the router.
RouterType	Indicates the router Level: l1, l2, or l1/2.
System ID	Indicates the system ID.
Max LSP Gen Interval	Indicates the maximum time between LSP updates in seconds.
Metric	Indicates if the metric is narrow or wide.
Overload-on-startup	Indicates the IS-IS overload-on-startup value in seconds. The overload-onstartup value is used as a timer to control when to send out Link State Packets (LSPs) with the overload bit cleared after IS-IS startup. The default value is 20 seconds.
Overload	Indicates if there is an overload condition.
Csnp Interval	Indicates the interval between CSNP updates in seconds.
PSNP Interval	Indicates the interval between PSNP updates in seconds.
Rxmt LSP Interval	Indicates the received LSP time interval.
spf-delay	Indicates an SPF delay in milliseconds. The default value is 100 milliseconds.
Router Name	Indicates the IS-IS name of the router.
ip source-address	Indicates the IP source address used for SPBM IP shortcuts.
ipv6 source-address	Indicates the IPv6 source address used for SPBM IP shortcuts.
ip tunnel source-address	Indicates the IP tunnel source address used for SPBM Fabric Extend.
Tunnel vrf	Indicates the name of the vrf that contains the tunnel endpoints.
ONA Port	Indicates the port to which the ONA device is attached. Note: The ONA port parameter is applicable only to the VSP 4450 Series.
ip tunnel mtu	Indicates the maximum size of a packet that can be transmitted through the IP tunnel.
Num of Interfaces	Indicates the number of interfaces on the router.
Num of Area Addresses	Indicates the number of area addresses on the router.
Num of Summary Address	Indicates the summary of the addresses on router.
inband-mgmt-ip Note: Exception: not supported on VSP 8600 Series or XA1400 Series.	Indicates the DvR management IP address for this node, in the DvR domain.
backbone	Indicates whether this node is part of the DvR backbone.
Dynamically Learned Area	For Fabric Area Network (FAN) members, specifies the IS-IS area that is dynamically learned from the neighbor‘s Hello PDU if the node does not have the IS-IS manual area configured.
FAN Member	Indicates whether the node is a member of the FAN.

show isis system-id

The following table describes the fields in the output for the show isis system-id command.


Parameter	Description
SYSTEM-ID	Shows the system ID. Output from this show command is from the global IS-IS configuration of the system ID. There is one system ID configured. The system ID is 6 bytes in length.

show isis net

The following table describes the fields in the output for the show isis net command.


Parameter	Description
NET	Shows the NET address. Output from this command is from the global IS-IS configuration of the manual area and the configuration of the system ID. There is only one manual areas defined and only one system ID. The manual area is from 1-13 bytes in length. The system ID is 6 bytes in length.
