TMM on active unit cores when it receives an HTTP/2 request when mirroring is configured.
TMM cores. Traffic disrupted while tmm restarts.
-- High availability (HA) configuration. -- Active unit received an HTTP/2 request. -- Mirroring is enabled.
Disable mirroring. Note: Connection mirroring is not supported in combination with the HTTP/2 profile. The system now checks for this combination and prevents it from being configured.
This release adds connection mirroring validation for the HTTP/2 profile. HTTP/2 virtual server validation fails if connection mirroring is enabled, and the system posts an error similar to the following: 01070734:3: Configuration error: Error configuring Virtual Server (/Common/vs1). Connection mirroring is not supported in combination with HTTP2 profile.
Previously, TMM cored on the active system when it received an HTTP/2 request and connection mirroring was enabled. Now, HTTP/2 Virtual Server validation fails if connection mirroring is enabled, and the system reports the following message in the LTM log: err mcpd[25742]: 01070734:3: Configuration error: Error configuring Virtual Server (/Common/vs_http). Connection mirroring is not supported in combination with HTTP2 profile. This is correct behavior, as connection mirroring is not supported in combination with the HTTP/2 profile.
