Juniper-ha SSG Series Cluster-id solutions to scarcity problems.Http://forums.juniper.net/t5/ScreenOS-Firewalls-NOT-SRX/Cluster-ID-issue-on-ssg140/m-p/15312//true(Answer from Juniper's official technician)By default, NSRP would support up to 8 cluster ID ' s and 8 VSD ' s. As noted in the previous entry, you can increase this with the Envar, but you need to use them in multiples of 8, and the combination of cluster ID ' s and VSD ' s cannot exceed . Y
Table-Level LockTable-level protection protects data. During transaction processing, table-level locks limit the addition, deletion, and modification operations on the entire table.

Oracle locks have the following modes:
0: None1: NULL2: Row-s row sharing (RS): Share table lock3: Row-X (RX): used for row Modification4: Share share lock (s): blocks other DML operations5: S/row-x dedicated shared rows (SRx): block other transaction operations6: exclusive dedicated (x): used for independent access

Recently, a customer's AAA was not correctly configured, causing him to be locked out of the device. Because it is a multi-switch stack unit in the production environment, it is not allowed to restart and ignore the configuration, remote operations are required to solve the problem, which undoubtedly increases the difficulty of solving the problem.
After several attempts, we found that some settings on Cisco ACS can bypass the authorization to access the device. We will share with you the situat
