Usage Guidelines

Usage Scenario

To check information about IS-IS interfaces, including the interface name, IP address, link status of each interface, run the display isis interface command. If verbose is specified, the output of this command also covers IS-IS parameter configurations for each interface, such as the CSNP broadcast interval, hello packet broadcast interval, and the number of IS-IS Hello packets sent by the neighbor before IS-IS should declare the neighbor Down.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display isis interface traffic-eng** command output
Item	Description
Interface	Type and number of an IS-IS interface.
Id	Circuit ID.
IPV4.State	IPv4 link status.
IPV6.State	IPv6 link status.
MTU	MTU of the interface.
Type	Type of interface: L1: Level-1 interface. L2: Level-2 interface. L1/L2: Level-1-2 interface.
DIS	Whether the interface is a Designated Intermediate System (DIS): No/No: The interface is not a DIS either in the Level-1 or Level-2 area. Yes/Yes: The interface is a DIS in both Level-1 and Level-2 areas. Yes/No: The interface is a DIS in the Level-1 area. No/Yes: The interface is a DIS in the Level-2 area. --: The interface is P2P, and it cannot be a DIS.
DIS Hello Timer Value	Interval at which the DIS sends Hello packets, which is one third of Hello Timer Value. The field takes effect only when the interface functions as the DIS.
Circuit MT State	Topology on the interface: Standard. IPv6.
SNPA Address	MAC address of the interface.
IP Address	Primary IPv4 address of the interface.
Csnp Timer Value	Interval at which the IS sends CSNPs, which can be set using the isis timer csnp command. Modifying the interval affects IS-IS route convergence.
Hello Timer Value	Interval at which the IS sends Hello packets, which can be set using the isis timer hello command.
Hello Multiplier Value	Number of sent IS-IS Hello packets that are not replied by a neighbor before the local device declares the neighbor Down. The value can be set using the isis timer holding-multiplier command. Because the value determines the hold time of IS-IS neighbor relationships, referring the usage guideline of the command before configuring the value is recommended.
LSP-Throttle Timer	Minimum interval at which LSPs are sent, which can be set using the isis timer lsp-throttle command.
Cost	IPv4 cost on an interface. The value is decisive in route selection.
Ipv6 Cost	Cost of an IPv6 interface. This field affects route selection in the IPv6 topology.
Priority	DIS priority on an interface, which can be set using the isis dis-priority command. The device with the highest DIS priority is selected as the DIS.
Retransmit Timer Value	Interval at which LSPs are resent, which can be set using the isis timer lsp-retransmit command.
Bandwidth-Value	Bandwidth of an interface. The value can be calculated using the following formula: Bandwidth-Value = 4294967296 x. high +. low. For example, if the value of. high is 1 and the value of. low is 705032704, Bandwidth-Value = 1 x 4294967296 + 705032704 = 5000000000. low: The maximum value is 4294967295. high: The maximum value is 4294967295.
Static Bfd	Status of static BFD: NO. YES.
Dynamic Bfd	Status of dynamic BFD: NO. YES.
MPLS TE Status	MPLS TE status: ON. OFF.
MPLS TE Cost	Link cost used by a TE interface.

TE Max Res Bandwidth	TE maximum reservable bandwidth.
TE Cost	Cost of a TE link.
INTF L1 TE Status	TE status on a Level-1 interface: ON. OFF.
INTF L2 TE Status	TE status on a Level-2 interface: ON. OFF.
INTF L1 IPv6 TE Status	IPv6 TE status on a Level-1 interface: ON. OFF.
INTF L2 IPv6 TE Status	IPv6 TE status on a Level-2 interface: ON. OFF.

Level-1 Unidirectional Delay Info	IPv4 unidirectional delay information on the Level-1 interface.
Level-1 IPv6 Unidirectional Delay Info	IPv6 unidirectional delay information on the Level-1 interface.
Metric Delay Status	Delay information advertisement status on the interface: ON. OFF.
Metric Link Loss Status	Whether packet loss measurement is enabled on Level-1 and Level-2 interfaces: ON. OFF.
Suppress Timer (Remain/Config)	Timer (in seconds) used to suppress delay information advertisement (remaining time before the timer expires/configured timer value).
Suppress Timer (Remain/Config)	Packet loss rate suppression timer (remaining time/configured time).
Current Used Delay (Min/Max)	Delay data (in microseconds) used on the current network (minimum delay/maximum delay).
Current Used Link Loss	Packet loss rate used on the current network.
Suppressed Delay (Min/Max)	Delay data (in microseconds) under suppression (minimum delay/maximum delay).
Suppressed Link Loss	Packet loss rate during suppression.
Receive Delay (Min/Max)	Delay data (in microseconds) received by the current interface (minimum delay/maximum delay).
Receive Link Loss	Packet loss rate received on the current interface.
Level-2 Unidirectional Delay Info	IPv4 unidirectional delay information on the Level-2 interface.
