Can I specify the port of the log host for receiving logs on S series switches

18

On an S series switch (except the S1700) that runs V200R008 or a later version, you can specify the TCP/UDP port number of the log host for receiving logs. The configuration command is info-center loghost ip-address port port-id. By default, the UDP port number is 514 and TCP port number is 6514.

The maximum number of log hosts that can receive logs sent by S series switches
The S series switches (except the S1700) can be configured to send logs to a maximum of eight log hosts (IPv4 and IPv6 log hosts), thus achieving mutual backup among the log hosts.

Can I log in to an S series fixed switch in a stack using the same method of logging in to a modular switch
Yes, you can log in to an S series fixed switch in a stack using the same method of logging in to a modular switch. Methods of logging in to a stack of fixed switches are as follows: Local login: Log in to the stack through the console port on any member switch. Remote login: Log in to the stack through the management port or another Layer 3 interface on any member switch. You can remotely log in to the stack using Telnet, STelnet, web, or SNMP if your operation terminal has a reachable route to the stack. Methods of logging in to a cluster of modular switches are as follows: Local login: Log in to the cluster from the console port on any MPU. Remote login: After reachable routes are configured, you can remotely log in to the cluster from a management interface on any SRU or a Layer 3 interface using Telnet, STelnet, web, or SNMP.

Does the log buffer of S series switches record all logs
The log buffer only records some logs. For S series switches (except the S1700), two factors determine the logs recorded by log buffer. - By default, the log buffer only records logs at levels lower than the warning level (level 4); therefore, logs at levels 0 to 4 are recorded in the log buffer, whereas logs at levels 5 to 7 are not recorded. You can run the info-center source { module-name | default } channel { channel-number | channel-name } log { state { off | on } | level severity } * command to configure the levels of logs that can be recorded in the log buffer. - The space of the log buffer is limited. If the number of logs in the log buffer reaches the maximum, new logs will replace the earliest logs in the log buffer. By default, the log buffer can hold a maximum of 512 logs. You can run the info-center logbuffer size size command to configure the maximum number as 1024.

Does the AR support periodical transmission of logs to the log host
No, the AR does not support periodical transmission of logs to the log host. However, the AR can send logs to the log host.
