EX Series switches do not support the collection and reporting of IPv6 transit
statistics.
IPv6 transit
statistics
extensiveInput errors on the interface:
• Errors—Sum of the incoming frame aborts and FCS errors.
• Drops—Number of packets dropped by the input queue of the I/O Manager
ASIC. If the interface is saturated, this number increments once for every
packet that is dropped by the ASIC's RED mechanism.
• Framing errors—Number of packets received with an invalid frame checksum
(FCS).
• Runts—Number of frames received that are smaller than the runt threshold.
• Policed discards—Number of frames that the incoming packet match code
discarded because they were not recognized or not of interest. Usually, this
field reports protocols that the Junos OS does not handle.
• L3 incompletes—Number of incoming packets discarded because they failed
Layer 3 sanity checks of the header. For example, a frame with less than
20 bytes of available IP header is discarded. L3 incomplete errors can be
ignored if you configure the ignore-l3-incompletes statement.
• L2 channel errors—Number of times the software did not find a valid logical
interface for an incoming frame.
• L2 mismatch timeouts—Number of malformed or short packets that caused
the incoming packet handler to discard the frame as unreadable.
• FIFO errors—Number of FIFO errors in the receive direction that are reported
by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably
malfunctioning.
• Resource errors—Sum of transmit drops.
