Cp To Cop Messaging; Interval; Ercd Records Dump - Avaya 8800 Troubleshooting Manual

Troubleshooting tool fundamentals

CP to COP messaging

When you enable Packet Tracing on the CP, a message is sent to the COP to internally enable
Packet Tracing on the specific RSP.
The message consists of the following:
• RSP number—the number of the RSP on which Packet Tracing is enabled. This
determines whether the Packet Tracing is ingress or egress.
Lane No.
Ingress-RSP
Egress-RSP
• slot number
• state—enable or disable
• interval—the number of seconds for which the Packet Tracing remains enabled

Interval

An optional parameter interval enables Packet Tracing for the desired number of seconds. The
value of the interval can be 1, 10, 30, 60, 120, or 300 seconds. When you enable Packet
Tracing, a timer is started on the COP, which runs for the interval number of seconds and
disables Packet Tracing after the interval number of seconds. When Packet Tracing is
disabled, the COP sends a trace disable message to the CP.

ERCD Records Dump

Ethernet Routing Switch 8800/8600 provides CLI and ACLI support for the following COP
debug commands:
• dump ercdRecord arp
• dump ercdRecord ip
• dump ercdRecord ip_subnet
• dump ercdRecord mac—When MAC is learned against a port , one MAC record is created
on the COP. The same entry is downloaded by the CP, to all the other slots available on
the Metro Ethernet Routing Switch 8800/8600. This command shows the learned MAC
entries for the specified port that are present on the COP, and the corresponding VLAN
