HP Comware 5 Debug Manual Vol 2

When you disable IS-IS and then enable it on VLAN-interface 100 of Router A, output similar to the
following example is generated:
<Sysname> debugging isis circuit-information
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] undo isis enable
[Sysname-Vlan-interface100] isis enable
ISIS-1-CIRC: Received Circuit OperState ON : Enabling the Circuit
ISIS-1-CIRC: The IP is set to UP for IS-IS on interface Vlan100
// The IP address took effect on the IS-IS interface.
# Enable debugging for the received IS-IS packets on Router A and Router B. The output in this example
was created when the following conditions exist:
•
Router A and Router B are interconnected and have established an IS-IS adjacency with each other.
•
Router A is elected as the DIS.
ISIS-1-SNP: CSNP Range from 0000.0000.0000.00-00 to ffff.ffff.ffff.ff-ff.
ISIS-1-SNP: Rxed L1 CSNP From 0000.0000.0001 (Vlan100)
ISIS-1-SNP: CSNP Range from 0000.0000.0000.00-00 to ffff.ffff.ffff.ff-ff.
ISIS-1-SNP: Rxed L2 CSNP From 0000.0000.0001 (Vlan100)
// Router B received CSNP packets within a maximum range of 0000.0000.0000.00-00 to
ffff.ffff.ffff.ff-ff.
ISIS-1-SNP: Sending L1 CSNP on Vlan100
ISIS-1-SNP: Sending L2 CSNP on Vlan100
// Router B sent CSNP packets.
# Enable local update debugging on Route A. The output in this example was created when the
following conditions exist:
•
VLAN-interface 100 on Router A is connected to VLAN-interface 100 on Router B.
•
An IS-IS process is created on Router A and Router B, and IS-IS is enabled on the interfaces.
When you enable IS-IS and then disable it on VLAN-interface 100, output similar to the following
example is generated:
<Sysname> debugging isis self-originate-update
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] undo isis enable
ISIS-1-UPDT: Deleting from the LSP Neighbour option, TLV 2
ISIS-1-UPDT: Circuit Down Vlan100
ISIS-1-UPDT: Deleting Address 100.1.1.0 from L1 LSPs, TLV: 128
ISIS-1-UPDT: Deleting Address 100.1.1.0 from L2 LSPs, TLV: 128
// The Neighbor TLV was deleted from the local LSPs, and the reachable TLV with an IP prefix of
100.1.1.0/24 was deleted from the local L1 and L2 LSPs.
[Sysname-Vlan-interface100] isis enable
ISIS-1-UPDT: Circuit Up Vlan100
ISIS-1-UPDT: Adding Address 100.1.1.0 into L1 LSPs, TLV: 128
ISIS-1-UPDT: Adding Address 100.1.1.0 into L2 LSPs, TLV: 128
ISIS-1-UPDT: Adding in the LSP Neighbour option, TLV 2
