VM Service has two sets of cipher suites: “Strong” and “Weak”. Strong suites are enabled by default.

Table 1.

To change the cipher suites, use the following commands:

  1. vla_tomcat_cipher -s STRONG to set “Strong” cipher suites

  2. vla_tomcat_cipher -s WEAK to set “Weak” cipher suites

  3. vla_tomcat_cipher -g to see the enabled set of cipher suites
