OS-CX switches support centralized authentication, authorization, and accounting for administrative access using RADIUS and TACACS, allowing administrators to control and audit management access through external AAA servers.

SNMP polling uses UDP port 161, which must be open between the Network Monitoring System and the CX switches to allow the collection of monitoring data.

LACP (Link Aggregation Control Protocol) is a protocol used to combine multiple physical network links into a single logical link, known as a link aggregation group (LAG). This increases the overall bandwidth between two network devices, providing redundancy and load balancing for traffic across the aggregated links. LACP is part of the IEEE 802.1AX standard (formerly 802.3ad), and its primary purpose is to manage the aggregation of links to improve network performance and reliability.

The output shows member 1 is the Conductor and member 2 is the Standby. If the Conductor (member 1) reboots, the Standby takes over the control-plane role to maintain stack operation, so member 2 becomes the Conductor.

When troubleshooting an LACP (Link Aggregation Control Protocol) issue where some links are not forwarding traffic, the first step should be to ensure that LACP is enabled on both ends of the link. LACP must be configured consistently on both switches for the aggregation to function correctly. If LACP is enabled on one switch but not the other, the links will not form a valid aggregated group, leading to issues like traffic not being forwarded and performance degradation.
