You want to remove one of your Brocade VDX 6740s from your VCS fabric in Logical Chassis mode. You issue the no vcs enable command on the VDX 6740 but the switch is not removed.
What would you do to resolve the problem?
A customer would like to manage their Brocade VDX switch but is having problems connecting from the Brocade Network Advisor server at IP address 10.10.30.15.

Referring to the exhibit, what are two reasons for this happening? (Choose two.)
Brocade Network Advisor has notified you that one of your ISLs between two Brocade VDXs is reporting a high number of errors. You log into the switch and clear the counters. You notice that the CRC and error counters are incrementing at a high rate.
What do these two errors indicate? (Choose two.)
You added a new Brocade VDX 6740 to an existing Brocade VCS Fabric in your data center. You connected the VDX 6740 to ports 3/0/11 and 3/0/12 on the existing fabric. After the switch boots, you realize it does not join the fabric. You examine the ISL status on the fabric as shown in the exhibit.
