Operational show commands

What it does: the CLI data that laptop-side ping/trace can't see. Key ones: `show interface` (CRC/input errors, drops, oper status, utilization) for flapping/erroring links; `show ip bgp` / `show route` for routing and BGP state; `show mac address-table` to locate a MAC to a switchport; syslog for events/flaps.

Use it for: the majority of real tickets — errors, route flaps, missing prefixes, locating a rogue device's port.

Notes: reach these through pyATS/Junos MCP (structured) or an SSH session.
