Command Mode

EXEC

Usage Information

The * in the mismatch output indicates a local node entry.

The show vlt mismatch dhcp-relay command displays the mismatch in the Global ip dhcp-relay information-option command.

The show vlt mismatch dhcp-relay command displays the presence or absence of Interface level ip dhcp-relay information-option configurations.
