H3C MSR Series

719
Syntax
In non-FIPS mode:
ssh2 algorithm key-exchange { dh-group-exchange-sha1 | dh-group14-sha1 |
dh-group1-sha1 } *
undo ssh2 algorithm key-exchange
In FIPS mode:
ssh2 algorithm key-exchange dh-group14-sha1
undo ssh2 algorithm key-exchange
Default
In non-FIPS mode:
SSH2 uses the key exchange algorithms dh-group-exchange-sha1, dh-group14-sha1, and
dh-group1-sha1 in descending order of priority for algorithm negotiation.
In FIPS mode:
SSH2 uses the key exchange algorithm dh-group14-sha1 for algorithm negotiation.

Parameters
dh-group-exchange-sha1: Specifies the key exchange algorithm
diffie-hellman-group-exchange-sha1.
dh-group14-sha1: Specifies the key exchange algorithm diffie-hellman-group14-sha1.
dh-group1-sha1: Specifies the key exchange algorithm diffie-hellman-group1-sha1.
Usage guidelines
If you specify the key exchange algorithms, SSH2 uses only the specified algorithms for algorithm
negotiation. The algorithm specified earlier has a higher priority during negotiation.
Examples
# Specify the algorithm dh-group1-sha1 as the key exchange algorithm for SSH2.
