Setting The Dscp Value For Packets Sent By The Ssh Server; Configuring The Switch As An Ssh Client; Ssh Client Configuration Task List; Specifying A Source Ip Address/Interface For The Ssh Client - HP 6125G Configuration Manual

Step
4. Set the SSH user
authentication timeout period.
5. Set the maximum number of
SSH authentication attempts.

Setting the DSCP value for packets sent by the SSH server

A field in an IPv4 or IPv6 header contains 8 bits and is used to identify the service type of an IP packet.
In an IPv4 packet, this field is called "Type of Service (ToS)." In an IPv6 packet, this field is called "Traffic
class." According to RFC 2474, the ToS field is redefined as the differentiated services (DS) field, where
a DSCP value is represented by the first six bits (0 to 5) and is in the range 0 to 63. The remaining two
bits (6 and 7) are reserved. When a packet is being transmitted, the network devices can identify its
DSCP value, and determines the transmission priority of the packet according to the DSCP value.
To set the DSCP value for packets sent by the SSH server:
Step
1. Enter system view.
2. Set the DSCP value for
packets sent by the SSH
server.

Configuring the switch as an SSH client

SSH client configuration task list

Task

Specifying a source IP address/interface for the SSH client

Configuring whether first-time authentication is supported
Establishing a connection between the SSH client and server
Setting the DSCP value for packets sent by the SSH client
Specifying a source IP address/interface for the SSH client
This configuration task allows you to specify a source IP address or interface for the client to access the
SSH server, improving service manageability.
To specify a source IP address or interface for the client:
Command
ssh server authentication-timeout
time-out-value
ssh server authentication-retries
