Input errors

Input errors on the interface:

• Errors—Sum of incoming frame aborts and frame check sequence (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 FCS.
• Runts—Number of frames received that are smaller than the runt threshold.
• Giants—Number of frames received that are larger than the giant 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.
• Resource errors—Sum of transmit drops.

detail extensive

Output errors

Output errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

• Carrier transitions —Number of times the interface has gone from down to up. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and then up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC is malfunctioning.
• Errors—Sum of the outgoing frame aborts and FCS errors.
• Drops—Number of packets dropped by the output 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.
• MTU errors—Number of packets whose size exceeded the MTU of the interface.
• Resource errors—Sum of transmit drops.

Flow error statistics (Packets dropped due to)

Packet drop statistics for the flow module.

• Address spoofing—Packet dropped when the screen module detected address spoofing.
• Authentication failed—Packet dropped because the IPsec Encapsulating Security Payload (ESP) or Authentication Header (AH) authentication failed.
• Incoming NAT errors—Packet dropped because the source NAT rule search failed, an invalid source NAT binding was found, or the NAT allocation failed.
• Invalid zone received packet—This counter is not currently in use.
• Multiple user authentications—Packet dropped if it matches more than one policy that specifies user authentication. (Sometimes packets are looped through the system more than once. Each time a packet passes through the system, that packet must be permitted by a policy.)
• Multiple incoming NAT—Packet dropped if source NATing is specified more than once. (Sometimes packets are looped through the system more than once.)
• No parent for a gate—This counter is not currently in use.
• No one interested in self packets—This counter is incremented for one of the following reasons:
  • The outbound interface is a self interface, but the packet is not marked as a to-self packet and the destination address is in a source NAT pool.
  • No service is interested in the to-self packet
  • When a zone has ident-reset service enabled, the TCP RST to IDENT request for port 113 is sent back and this counter is incremented.
• No minor session—Packet dropped because no minor sessions are available and a minor session was requested. Minor sessions are allocated for storing additional TCP state information.
• No more sessions—Packet dropped because there were no more free sessions available.
• No NAT gate—This counter is not currently in use.
• No route present—Packet dropped because a valid route was not available to forward the packet.
• No SA for incoming SPI—Packet dropped because the incoming IPsec packet's security parameter index (SPI) does not match any known SPI.
• No tunnel found—Packet dropped because a valid tunnel could not be found.
• No session for a gate—Packet dropped by an ALG.
• No zone or NULL zone binding—Packet dropped because its incoming interface was not bound to any zone.
• Policy denied—The error counter is incremented for one of the following reasons:
  • Source or destination NAT (or both) has occurred and policy says to drop the packet.
  • Policy specifies user authentication, which failed.
  • Policy was configured to deny this packet.
• Security association not active—Packet dropped because an IPsec packet was received for an inactive SA.
• TCP sequence number out of window—TCP packet with a sequence number failed the TCP sequence number check that was received.
• Syn-attack protection—Packet dropped because of SYN attack protection or SYN cookie protection.
• User authentication errors—Packet dropped because policy requires authentication; however:
  • Only Telnet, FTP, and HTTP traffic can be authenticated.
  • The corresponding authentication entry could not be found, if web-auth is specified.
  • The maximum number of authenticated sessions per user was exceeded.
