Inleiding

Dit document beschrijft hoe u problemen kunt oplossen en het Taal van de Opdracht van de Gereedschap (TCL) script genaamd tm_wanmon.tcl die in de IOS beelden is ingesloten voor Cisco IOS 1000 Series Connected Grid Router (CGR). Dit script, indien ingeschakeld, fungeert als WAN-bewakingssoftware (Wide Area Network) voor WAN-interfaces en voert steeds indringender handelingen uit om te herstellen van een WAN-link of een tunnelstoring.

Wanneer WANMON op de router wordt geactiveerd, wordt het script afgeleid in het sys:/eem_policy/folder en het script kan worden bekeken met het gebruik van deze opdracht; Router#more.sys:eem_policy/tm_wanmon.tcl.

Voorwaarden

Vereisten

Cisco raadt u aan het TCL-script in te schakelen zoals uitgelegd in deze documentatie; http://www.cisco.com/c/en/us/td/docs/routers/connectedgrid/cgr1000/ios/software/15_4_1_cg/WANMon.html.

Minimale software: Cisco IOS-softwarerelease 15.4(1)CG

Gebruikte componenten

De informatie in dit document is gebaseerd op CGR1120/CGR1240.

De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.

Methodologie voor probleemoplossing

Wanneer WANMON wordt gevormd en op een CGR loopt, kan het zuiveren voor het script worden geactiveerd wanneer u deze configuratie aan de configuratie van het apparaat toevoegt:

Router(config)#event manager environment wanmon_debug all

Verifiëren scripts

Router(config)#event manager policy tm_wanmon.tcl authorization bypass
Router(config)#event manager environment wanmon_if_list1 {GigabitEthernet2/1 {recovery {5 25} {90 180} {600 100}} }
Router(config)#event manager environment wanmon_debug all

Vaak voorkomende kwestie tijdens het uitvoeren van scripts

Synbelastingfout

Een situatie kan zich voordoen waar je denkt dat WANMON werkt wanneer het wordt geconfigureerd, maar het heeft geen effect. In een omgeving waar het WANMON - script niet correct werkte, werd deze debug-uitvoer bijvoorbeeld waargenomen:

In overeenstemming met deze uitvoer, wordt het script niet uitgevoerd vanwege het feit dat er een ruimte is tussen de naam van de interface en de nummers. De opdracht die deze fout veroorzaakte was:

event manager environment wanmon_if_list1 {gig 2/1 {recovery {5 25} {90 180} {400 100}} }

De juiste configuratie moet zijn:

event manager environment wanmon_if_list1 {gig2/1 {recovery {5 25} {90 180} {400 100}} }

IPSLA-laag (Internet Protocol Service Level Agreement)

Als WANMON meerdere interfaces met IPSLA instelt.

IPSLA operaties, het kan lastig zijn om onmiddellijk te bepalen waar de mislukking is. Dit debug uitvoer toont wat gebeurt wanneer twee interfaces door WANMON met IP SLA op elke interface worden gecontroleerd:
