HP Comware 5 Debug Manual Vol 3

Table 185 Output from the debugging rrpp packet command
Field
Description
Port interface-type
interface-number String1 packet
of domain domain-id
ringring-id.(Length: ULONG,
Type: String2) String3
Packet debugging information:
• interface-type interface-number—Interface type and interface number.
• String1—Packet direction. This field can be Rcvd (indicating received
packets) or Send (indicating sent packets).
• domain-id—RRPP domain ID.
• ring-id—RRPP ring ID.
• ULONG—Packet length.
• String2—Packet type: Health, Link-Down, Complete-Flush-FDB,
Common-Flush-FDB, Edge-Hello, or Major-Fault.
• String3—The packet content in hexadecimal format.
Examples
# Enable debugging for RRPP errors on one of the two master nodes. The output in this example was
created when the following conditions exist:
•
Configure two master nodes on an RRPP ring, and configure the other devices as the transit nodes.
•
Enable RRPP on all the devices, and enable all the RRPP rings.
<Sysname> debugging rrpp error
*0.2484426 Sysname RRPP/8/RCVPKTERR:
Received packet on port Ethernet1/1 error ! Reason : a conflicting master node of current
ring was detected .
*0.2485436 Sysname RRPP/8/RCVPKTERR:
Received packet on port Ethernet1/1 error ! Reason : a conflicting master node of current
ring was detected .
// Two master nodes were detected on the ring.
# Enable debugging for RRPP events on Device B. The output in this example was created when Device
A operates as a transit node on the primary ring, with the RRPP ring enabled and RRPP protocol disabled.
When you configure Device B as the master node of the primary ring, with the RRPP ring and RRPP
protocol enabled, output similar to the following example is generated:
<Sysname> debugging rrpp event
*0.6664449 Sysname RRPP/8/EVT:
Domain 1 ring 1 is activated .
// Ring 1 of domain 1 was activated.
*0.6667140 Sysname RRPP/8/EVT:
Domain 1 ring 1 turns to fault for fail-timer timeout .
// The ring failed because the master node received no health packet of its own before the Fail timer
expired.
*0.8708437 Sysname RRPP/8/EVT:
Domain 1 ring 1 recovered for health packet .
// Ring 1 in domain 1 on Device B recovered after RRPP was enabled on Device A.
# Enable debugging for RRPP fast detection. The output in this example was created when transit nodes
and the assistant-edge node are configured for the primary ring.
