Powerman-1r Testing
Xetron delivered ROCEM version 1.1 for 3560G. Testing ROCEM for operational use on JQJADVERSE. Operator was not able to provide a configuration for the 3560G - we only know that this 3560G is a core switch with a router on a stick configuration and in a VTPVLAN Trunk Protocol enviroment. Conop will be to first use ROCM to survey device and then subsequently use ROCEM to throw HG. We are testing with a 3560G-24-PS, although Xetron's readme lists this ROCEM release is for 3560G-24-TS. It is not believed that the power over ethernet feature should affect the implant.
Testing Summary
- Readme needs to be changed - show switch detail does not exist in this IOSApple operating system for small devices version
- Exit from ROCEM interactive session logs SNMPSimple Network Management Protocol trap for connection close to trap server
- While ROCEM interactive session active, credentials which normal login with privilege level 15 actually login with privilege level 1. Attempts to enable produce error: Error in authentication
- While ROCEM interactive session active, new and existing telnet sessions are logged (this is not expected based on Operational Use Notes)
Progress/Notes
- Smoke Test - Survey 3560G with ROCEM
- 3560G is configured to use AAASecurity Server from Cisco server to authenticate users as well as authorize commands and log all commands entered
- 3560G is configured to log snmp traps and syslogs to Solarwinds
- Output of "who" command before ROCEM shows my console session and my vty session on line 1
3560G#who
Line User Host(s) Idle Location
0 con 0 cisco idle 00:07:52
* 1 vty 0 root idle 00:00:00 10.9.8.96Interface User Mode Idle Peer Address
3560G#
- Verified that AAASecurity Server from Cisco is logging show commands when entered in 3560G through regular telnet session
- Followed Xetron Powerman-1R readme procedure to use ROCEM to execute show commands
- ./rocem_c3560-ipbase-mz.122-35.SE5.py -i -f fill.bin 192.168.111.1
- Entered y to proceed
- 3560# prompt appeared - no creds were netered
- Executed show commands from readme successfully - show switch detail does not exist in this IOS. AAA does not log show commands entered through ROCEM to tac_accounting.log, no syslogs or SNMPSimple Network Management Protocol traps generated, however AAASecurity Server from Cisco does log the connection in /var/log/syslog. This is expected behavior (see Operational Use Notes).
-
Output of "who" command shows ROCEM vty session from ICON-CT IP and no username:
3560G#who
Line User Host(s) Idle Location
0 con 0 root idle 00:04:10
* 1 vty 0 root idle 00:00:00 10.9.8.96
2 vty 1 idle 00:00:02 172.20.12.22
-
Typed exit at ROCEM prompt - session closed, no logs generated to AAASecurity Server from Cisco server. Output of "who" shows vty session for ROCEM is gone. No logs in 3560G logging buffer. SNMP trap for the connection close is logged:

Performance Test - Survey 3560G with ROCEM
-
Established traffic with IXIA to simulate network conditions on the device and repeated Test 1 procedure
- 900Mbps with 100000 max simultanoeous and per second superflows with constant data rate
- Breaking Point Enterprise traffic profile
- 11 minute test
- Baseline CPU without IXIA traffic or ROCEM activity - CPU utilization for five seconds: 5%/0%; one minute: 5%; five minutes: 5%
- With IXIA traffic, CPU levels are the same - CPU utilization for five seconds: 5%/0%; one minute: 5%; five minutes: 5%
-
With IXIA traffic - only small increase in five second CPU spikes at the beginning of the test -
2 2
67955055555555 Observed small spike in five second CPU to 15% during ROCEM survey in output of show proc cpu hist - this increase was also observed when entering the survey commands through regular telnet session
- Did not observe any log of ROCEM activity to syslog buffer, AAASecurity Server from Cisco server, or trap server with the exception of connection close trap noted in Step 1g.
-
Established traffic with IXIA to simulate network conditions on the device and repeated Test 1 procedure
- Ad-hoc Test - Login to console while ROCEM set
- Established ROCEM interactive session on 3560G
- At console window, hit enter to bring up username prompt
- Enter username, and get password prompt
- Enter password - expected result - logged in with privilege 15. Actual result, logged in as privilege level 1. Type enable, but 3560G does not accept the enable password. Can't get into enable mode. Error message received - Error in authentication. Login in logged to AAASecurity Server from Cisco server.
- Exited ROCEM interactive session - must logout from privilege 1 mode and enter username and password again, this time with expected result of privilege level 15.
- Ad-hoc Test - Login via telnet during ROCEM interactive session
- same result observed as above - cannot get into enable mode with root user during ROCEM interactive session. Logged in as privilege level 1 and cannot get authenticated to enable mode. Exited ROCEM interactive seesion and exit and attempt to login again to restore expected result.
- Ad-hoc Test - Fill up vty lines during ROCEM interactive session
- Establish ROCEM interacive session
- Establish 15 more telnet sessions with Target Device (in priv level 1)
- Attempt another connection - connection is refused - expected behavior
- Exit ROCEM and attempt another connection again - this time connection is successful, priv level 15.
- Ad-hoc Test - SNMPSimple Network Management Protocol traps sent during interactive session
- During an interactive session, bounced an interface and saved config to generate SNMPSimple Network Management Protocol traps - as per Operational Use Notes, no SNMPSimple Network Management Protocol trap generated during interactive session
- Ad-hoc Test - Logging of logins during interactive session
- Established interactive session and then logged in via telnet and console - start/stop of logins were logged to AAASecurity Server from Cisco server. This is not expected because Operational Use Notes state that "While an interactive session is active, logging is disabled for all existing and new telnet sessions."
- Show commands entered from a regular telnet session while interactive ROCEM session active also log to AAASecurity Server from Cisco server.
- Test EAREnterprise Archive 4694 - Confirmed
- Created a user larry in tac_plus and denied show commands, assigned privilege level 1
- Enabled tac_plus autorization and verified that larry is not authorized to issue show ver
- Established interactive session.
- Verified that larry is now authorized to issue show commands
- Exited interactive session and verified that larry can no longer issue unauthorized by AAASecurity Server from Cisco commands
