Chapter 47: Monitoring Redundant CFEBs
Figure 233: M10i Router CFEB Location
CFEBs are hot-pluggable. Removing the standby CFEB has no effect on router
function. If the active CFEB fails or is removed from the chassis, the effect depends
on how many CFEBs are installed:
! If there is one CFEB, forwarding halts until the CFEB is replaced and functioning
again. It takes approximately one minute for the replaced CFEB to boot and
become active. Reading in router configuration information can take additional
time, depending on the complexity of the configuration.
! If there are two CFEBs, forwarding halts while the standby CFEB boots and
becomes active, which takes approximately one minute. Synchronizing router
configuration information can take additional time, depending on the
complexity of the configuration.
