The show isis command displays the following information:
| Output field | 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. | 
| 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 | 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. | 
| Hello Padding | Indicates IS-IS hello packets are padded to detect mismatched MTUs on adjacencies. | 
| Multi-area OperState | Indicates the Multi-area SPB operational state as: 
 | 
| Multi-Area Flags | home-always-up — Indicates that the boundary node forwards traffic from the UNIs to the remote-area and from the remote-area to the UNIs without requiring an established adjacency in the home area. | 
| Designated BN Hostname | Specifies the hostname of the designated boundary node. | 
| Designated BN Home System ID | Specifies the system ID of the designated boundary node in the home area. | 
| Designated BN Remote System ID | Specifies the system ID of the designated boundary node in the remote area. |
