SyncFrames
SyncframesareexchangedbetweencollocatedODUsusingLaye r‐2broadcasting.
Domain
Topreventnetworkflooding,eachgroupofcollocatedODUsisconfiguredwithaninternal
“domainname”.Thedefaultnamemustbechangedtopreventsyncframesbeingreceived
overtheLANbyanotherODU,whichcouldbethenmistakenlyconfiguredasaclientofan
HSMatthewronglocation.
Discovery
DiscoverybytheHSMandHSCsisprovidedusingthefollowingchoiceoffilters:
UsingdiscoveryattheHSM,youcanselectonlythoseHSCsintheHSM’sdomain;when
configuringanewHSCyoumayusediscoverytopickthecorrectHSM.
VLAN
VLANisusedtoseparatesyncframesfromtrafficsoastogivesyncframeshighestpriority.If
youhavecollocatedODUsrunningclosetofullcapacity,failuretodoso,wouldresultin
excessivejitteranddroppedtrafficframes.
Caution
VLANTaggingshouldnotusetheVLANIDusedbyHSSoEandviceversa.
