Displaying IPv4 IS-IS information
LSP Sequence Number Skipped The number of times the Brocade device received an LSP with a
sequence number that was more than 1 higher than the sequence
number of the previous LSP received from the same neighbor.
LSP Max Sequence Number Exceeded The number of times the Brocade device attempted to set an LSP
sequence number to a value higher than the highest number in the
CSNP sent by the Designated IS.
Level-1 Database Overload The number of times the Level-1 state on the Brocade device changed
from Waiting to On or from On to Waiting.
•
Waiting to On – This change can occur when the Brocade device
recovers from a previous Level-1 LSP database overload and is
again ready to receive new LSPs.
•
On to Waiting – This change can occur when the Brocade device’s
Level-1 LSP database is full and the Brocade device receives an
additional LSP, for which there is no room.
Level-2 Database Overload The number of times the Level-2 state on the Brocade device changed
from Waiting to On or from On to Waiting.
•
The change from Waiting to On can occur when the Brocade device
recovers from a previous Level-2 LSP database overload and is
again ready to receive new LSPs.
•
The change from On to Waiting can occur when the Brocade
device’s Level-2 LSP database is full and the Brocade device
receives an additional LSP, for which there is no room.
Our LSP Purged The number of times the Brocade device received an LSP that was
originated by the Brocade device itself and had age zero (aged out).
PDU Drop Count
CSNP Auth Failures The number of CSNP Authentication failures recorded for Level-1 and
Level-2. This counter will only be displayed if it has a value greater than
zero.
PSNP Auth Failures The number of PSNP Authentication failures recorded for Level-1 and
Level-2. This counter appears only if it has a value greater than 0.
HELLO Auth Failures The number of HELLO Authentication failures recorded for Level-1 and
Level-2. This counter will only be displayed if it has a value greater than
zero.
Adjacency not found The number of PDUs dropped at both Level-1 and Level-2 because there
is no valid adjacency on the interface where they were received. This
counter will only be displayed if it has a value greater than zero.
Adjacency Level Mismatch The number of PDUs dropped at both Level-1 and Level-2 because the
adjacency from which the PDU is received has a different level than the
PDU level. This counter will only be displayed if it has a value greater
than zero.
IS Level Mismatch The number of PDUs dropped at both Level-1 and Level-2 because the
IS-IS router level mismatches with the PDU level received. This counter
will only be displayed if it has a value greater than zero.
Length Too Short The number of PDUs dropped at both Level-1 and Level-2 because the
received PDU length is less than the standard PDU header length. This
counter will only be displayed if it has a value greater than zero.
