Information and troubleshooting tools
Tools are available to help you retrieve information about SMC and troubleshoot.
smc-tools
The smc-tools package provides commands that help you to manage connections that use the SMC
protocol. You can obtain this package at github.com/ibm-s390-linux/smc-tools.
- Use the smcd info and smcr info commands to verify the setup and obtain information on the capabilities of the hardware and Linux®.
- Use the smcd and smcr commands to investigate your SMC links, link groups, and devices.
Wireshark
To help with troubleshooting, you can use the open source tool Wireshark to analyze SMC handshake traffic. The traffic is visually presented in the tool. The network packets sent during the SMC handshake are presented in human readable format with explanatory titles.
You can also use tcpdump to capture handshake traffic.
