WLAN High Availability Flashcards
The port channel will stay up when at least one member interface is up if all go down so will the LAG itself? True/False
True
Cisco WLC LAG consists of distribution system ports? True/False
True
Redundancy ports and Redundancy Management Interfaces (RMIs) are ports used in Stateful Switchover (SSO) setups. True/False
True
A Cisco WLC does not support link aggregation negotiation protocols like PAgP and LACP. Only static channels can be configured ? True/False
True
In SSO setups, WLCs use their redundancy port to check peer reachability by sending UDP keepalive messages every 100msec, not the redundancy management interface. True/False
True
The Redundancy Management Interface (RMI) is used to check the health of the Active WLC via the network infrastructure once the Active WLC stops responding to the UDP keepalive messages sent via the redundant port? True/False
True
A SSO hot-standby WLC can also be configured with an HA SKU license, which allows the AP-count license info to be pushed from the active to the standby WLC. In the event of a failure, the HA SKU license lets all the APs join and starts a 90-day counter. After 90 days, the controller will start sending warning messages to the network administrator. It will not disconnect the APs? True/False
True
The WLC high availability design that uses an active/hot-standby approach is SSO Stateful Switchover? True/False
True
The default priority for a guest anchor controller is 3? True/False
True
Priority values for a guest anchor controller range from 1 (high) to 3 (low), or primary, secondary or tertiary? True/False
True
An AP does not fall back from a tertiary WLC to a secondary WLC, only directly to a primary WLC. Cisco implemented this is to reduce downtime and flapping between WLCs? True/False
True
