2x100G XPP ILKN monitoring
The 2x100G XPP ILKN monitoring feature will monitor CRC errors in the Interlaken link / interface between XPP1 and XPP2 in 2 packet
processors for the 2x100G Ibzian card.
In 2x100G cards, CRC errors on the Interlaken link between iXPP1 and iXPP2 in the packet processor result in packet drops. The
2x100G XPP ILKN monitoring feature will generate syslog and SNMP traps if software reads more than configured drops on ILKN links
between iXPP1 and iXPP2. Syslog and SNMP traps display the number of packet drops in the Interlaken interface and CRC errors in
lane groups.
Two 100G ports are available. For each port:
• One XPP (with two internal ingress XPPs, iXPP1, iXPP2, and an egress XPP) is present to perform packet processing. This
feature polls for Interlaken errors between ingress XPPs, iXPP1, and iXPP2.
• Two identical CXPP1x100G packet processors are present to perform 200Gbps packet processing.
SYSLOG and SNMP traps are generated if packet drops result from CRC errors in the Interlaken link / interface between iXPP1 and
iXPP2. The affected ports are shutdown if the Interlaken link / interface was configured through the new CLI configuration command
based on the following factors:
• The option to shutdown the affected ports is configured using the new global configuration command.
• The option to disable the feature is configured using the new global configuration command.
Syslog and SNMP traps are generated once the packets drop are seen because of Interlaken CRC errors. The syslog/SNMP trap is
generated once every 3 minutes with the following information:
• Indicating the number of packet drops and CRC errors in each lane group.
• Indicating if ports are not disabled by the port shut down option.
