Troubleshooting
Using the Event Log for Troubleshooting Switch Problems
System
Module
netinet Network Internet: Monitors the creation of a route or an
Address Resolution Protocol (ARP) entry and sends a log
message in case of failure.
pagp Ports Aggregation Protocol (PAgP): Obsolete. Replaced by
LACP (802.3ad). Not used for logging messages in software
release K.13.
ports Port status and port configuration features, including mode
(speed and duplex), flow control, and security settings.
Port messages include events on Power Over Ethernet (POE)
operation and transceiver connections with other network
devices.
radius RADIUS (Remote Authentication Dial-In User Service)
authentication and accounting: A network server is used to
authenticate user-connection requests on the switch and
collect accounting information to track network resource
usage.
snmp Simple Network Management Protocol: Allows you to manage
the switch from a network management station, including
support for security features, event reporting, flow sampling,
and standard MIBs.
sntp Simple Network Time Protocol: Synchronizes and ensures a
uniform time among interoperating devices.
ssh Secure Shell version 2 (SSHv2): Provides remote access to
management functions on a switch via encrypted paths
between the switch and management station clients capable
of SSH operation.
SSH messages also include events from the Secure File
Transfer Protocol (SFTP) feature. SFTP provides a secure
alternative to TFTP for transferring sensitive information, such
as switch configuration files, to and from the switch in an SSH
session.
ssl Secure Socket Layer Version 3 (SSLv3), including Transport
Layer Security (TLSv1) support: Provides remote web access
to a switch via encrypted paths between the switch and
management station clients capable of SSL/TLS operation.
stack Stack management: Uses a single IP address and standard
network cabling to manage a group (up to 16) of switches in
the same IP subnet (broadcast domain), resulting in a reduced
number of IP addresses and simplified management of small
workgroups for scaling your network to handle increased
bandwidth demand.
