Displaying IPv4 IS-IS information
The l1 and level1 parameters display the Level-1 LSPs only. You can use either parameter.
The l2 and level2 parameters display the Level-2 LSPs only. You can use either parameter.
The show isis database summary display shows the following information.
TABLE 44 IS-IS summary LSP database information
This field... Displays...
LSPID The LSP ID, which consists of the source ID (6 bytes), the pseudonode (1
byte), and LSPID (1 byte).
NOTE: If the address has an asterisk ( * ) at the end, this indicates that
the LSP is locally originated.
LSP Seq Num The sequence number of the LSP.
LSP Checksum The checksum calculated by the device that sent the LSP and used by
the Brocade device to verify that the LSP was not corrupted during
transmission over the network.
LSP Holdtime The maximum number of seconds during which the LSP will remain
valid.
NOTE: The IS that originates the LSP sets the timer for the LSP. As a
result, LSPs do not all have the same amount of time remaining
when they enter the Brocade device’s LSP database.
ATT A 4-bit value extracted from bits 4 – 7 in the Attach field of the LSP.
P The value in the Partition option field of the LSP. The field can have one
of the following values:
•
0 – The IS that sent the LSP does not support partition repair.
•
1 – The IS that sent the LSP supports partition repair.
OL The value in the LSP database overload field of the LSP. The field can
have one of the following values:
•
0 – The overload bit is off.
•
1 – The overload bit is on, indicating that the IS that sent the LSP is
overloaded and should not be used as a IS-IS transit router for that
level.
