Session & Interface counters

get session

> show security flow session

get interface

> show interface terse

get counter stat
get counter stat <interface>

> show interface extensive
> show interface <interface> extensive

clear counter stat

> clear interface statistics <interface>

Debug & Snoop

debug flow basic

# edit security flow
# set traceoptions flag basic-datapath
# commit

-creates debugs in default file name: /var/log/security-trace

set ff

# edit security flow
# set traceoptions packet-filter

Packet-drop is a feature that will be added

get ff

> show configuration | match packet-filter | display set

get debug

> show configuration | match traceoptions | display set

get db stream

View stored log: (recommended option)
> show log <file name> (enter h to see help options)
> show log security-trace (to view 'security flow' debugs)
> show log kmd (to view 'security ike' debugs)

‘monitor stop' stops real-time view , but debugs are still collected in log files

clear db

> clear log <filename> (clears contents of file)

Use ‘file delete <filename> to actually delete file>

undebug <debug> (stops collecting debugs)

# edit security flow
# deactivate traceoptions OR # delete traceoptions (at the particular hierarchy)
# commit

Deactivate makes it easier to enable/disable.

Use activate traceoptions to activate.

undebug all

Not available. You need to deactivate or delete traceoptions separately.

debug ike detail

> request security ike debug-enable local <local gw> remote <remore peer> level 7

-creates debugs in default file name: kmd

snoop (packets THRU the Junos OS device)

Use Packet Capture feature for branch, refer to KB11709

For High-end SRX (SRX1xxx/3x00/5x00), refer to KB21563

snoop (packets TO the Junos OS device)

> monitor traffic interface <int> layer2-headers
write-file option (hidden)
read-file (hidden)

-Only captures traffic destined for the RE of router itself.

- Excludes PING .

Event Logs

get event

> show log messages
> show log messages | last 20 (helpful cmd because newest log entries are at end of file)

 On SRX, default will only show critical level messages.  The correct syslog level must be configured, if more detailed logs are required.

get event | include <string>

> show log messages | match <string>
> show log messages | match “<string> | <string> | <string>”
Examples:
> show log messages | match “error | kernel | panic”
> show log messages | last 20 | find error

Note: There is not an equivalent command for ‘get event include <string>'.

match displays only the lines that contains the string

find displays output starting from the first occurrence of the string

clear event

> clear log messages

> show log

Config & Software upgrade

get config

> show config (program structured format)
> show config | display set (set command format)

get license

> show system license keys

get chassis (serial numbers)

> show chassis hardware detail

> show chas environment
> show chas routing-engine

exec license

> request system license [add | delete |save]

 Does not require a reboot on SRX, but does on ScreenOS

unset all

# load override /var/tmp/test.cfg (or full path of config file)

-TFTP is not supported. Use only FTP, HTTP, or SCP.

save software from tftp <tftp_server> <screenosimage> to flash

> request system software add
Example:
request system software add ftp:10.10.10.129/jsr/junos-srxsme-18.4R3-S2.tgz reboot

-TFTP is not supported. Use only FTP. HTTP, or SCP.
-Use ‘request system software rollback' to rollback to previous s/w package
