MX Routers
EX Switches
Helpful shell commands
ifmon
Time-elapsing interface counters: i/o bytes, i/o packets, errors, etc.
Pass the interface name when calling the command.
Usage: ifmon [-v] [-JL <lrname>] [interface]
What do the other flags do..?
iftop
Time-elapsing overview of interface counters: for all interfaces
Gives each port's rate in pps or bps, etc.
Usage: iftop [-v] [-d]
- -v : shows version
- -d : same as running without arguments, but adds interface descriptions
mtr
Yes.. Juniper actually includes mtr: pass it a hostname, watch a time-lapse
traceroute occur. Lookup the details online; widely available tool.
tcpdump
Juniper includes a modified version of tcpdump; again, look it up elsewhere.
lcdd: Line Card Daemon
"lcdd" from a shell (not the cli) connects you to various other parts of the switch,
including the software forwarding infrastructure (sfid), chassis manager (chassism),
and the virtual chassis system (vccpd). You don't need to be root to get into these.
The general idea is:
> lcdd 0 <area>
Where area is one of the above/below items. The digit (0) is the FPC slot number. EX switches only have FPC0.
sfid: Software Forwarding Infrastructure
chassism: Chassis Manager
vccpd: Virtual Chassis'
vty: Shell out to other parts of the system
"vty fpc0": connect to PFE
