What is msiHostTosUnreachable?
This read-only Counter32 counts ICMP Host Type-of-Service Unreachable report frames attributed to this row's MAC address (MacIndex) in the msi ICMP-report history table. Because this is broken out per host in the matrix rather than only as a switch-wide ICMP total, an admin can trace a specific ICMP condition back to the exact machine causing or experiencing it. An admin would notice msiHostTosUnreachable climbing for one row and investigate a host whose QoS-tagged traffic can't reach a destination host, relevant when diagnosing a TOS/DSCP-based routing issue.
