EFM Bonding Protection Definition
EFM Bonding Protection is a Layer 2 application used to protect traffic carried by those access
modules that include an EFM Bonding Engine as part of their feature set. EFM Bonding
Protection will not work for access modules that do not have this feature. The purpose of EFM
Bonding is the protection of traffic going to and from a particular slot, and not the access
module in that slot.
In an EFM Bonding Protection configuration, the Total Access 5000 EFM Protect Module is
installed in a Total Access 5000 shelf. Once the module is installed, it must be configured so it
can protect traffic going to and from a module in a specific slot. By creating an EFM Bonding
Group, traffic to and from a group of slots/access modules can also be protected. As an added
feature, EFM Bonding Protection also allows each of these groups and/or access modules
within a group to have a priority assigned to the traffic going to and from that access module
or group. For example, assume that all the access modules are being protected by the EFM
Protect Module in slot 11. The access modules in slot 1 to 8 have their priority set to 1 (priority
levels range from 1 to 32 where 32 is the highest priority), and those access modules in slots 17
to 21 have a priority level of 10. If one of the access modules in slots 1 to 8 goes offline, their
traffic will switch over to the EFM Protect Module. The traffic will continue to pass through
the EFM Protect Module until the access module that went offline comes back online, or an
access module in slots 17 to 21 goes offline. If that occurs, the EFM Protect Module will switch
to the slot/access module with the higher priority.
An example of how this configuration could be used is displayed in Table 4‐7.
