Spectrum Policy Manager

[Legacy User]

Suppose there existed a custom created Spectrum global policy/rule which has the two settings:

   1) 'GeneratePortStatusAlarms' (0x12a54) attributes to NO.  

   2) 'AlarmOnLinkDownTrap(0x11fc2) 0

 

for all ports (i.e. All network gear and systemEdge agent monitored hosts). The policy is said to have affected approx. 690K models.

For Spectrum SMEs, what would be your recommended ways to 'turn' port monitoring back on wisely without getting flooded with false positive alarms?

 

Thanks,

Charles

Hi Charles,

 

create a Global Collection "Connected_Ports" with Model Class = Port and NetworkLinkType != No Link to get all ports which have a modeled pipe in Spectrum. Then, assign this GC to a policy which enables the "alarming" attributes. Also refer to https://www.ca.com/us/services-support/ca-support/ca-support-online/knowledge-base-articles.TEC1074036.html.

 

Change your existing global policy to include only Ports with NetworkLinkType = No Link.

 

Alternatively, what we have also done for customers is to create an Event Procedure which resets the port alarming attributes when a port leaves the "Connected_Ports"  GC. That way, you don't have a huge GC with unconnected ports.

Would you mind sharing the Event Procedure you wrote to the community?

Hi Christophe,

 

here you go - I just tested it to verify that it works. the Event Procedure resets the Port Alarming, Port Trap Processing and some Port Thresholds:

 

0x110a04 E 50 R CA.EventCondition, "({v 2} == {S \"Connected_Ports\"})" , "0xffff0002  -:-"

0xffff0002 E 50 P \
" And( WriteAttribute( {C CURRENT_MODEL}, {H 0x11fc2}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12da6}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12952}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x1294e}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12951}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x1294d}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12be5}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12da4}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12da3}, { I 0}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12957}, { B FALSE}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x12a54}, { B FALSE}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x11ace}, { B FALSE}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x129f8}, { B FALSE}), \
  And( WriteAttribute( {C CURRENT_MODEL}, {H 0x1280a}, { B FALSE}), \
       WriteAttribute( {C CURRENT_MODEL}, {H 0x11dd8}, { B FALSE})))))))))))))))"
