What is the confirmed definition of "ge_err_in_pkt_drop" on the Brocade 7840 portstatsshow geX.
The FOS command guides (v7.4, 8.0, 8.1) do not list this counter under portstatsshow command.

The packet drops are related to pause frames received from peer ge_stat_rx_pause_frms.
ge_err_in_pkt_drop counter can be ignored as this is not errors by itself when ge_stat_rx_pause_frms is incrementing too.
I have 1 question and 1 comment:
Question: Where can I find the Brocade document defining "ge_err_in_pkt_drop" for the 7840 using IP-extension.
Comment: I do not follow the error description provide.
In my scenario the Ge10 and Ge11 interfaces are aggregated from local network side. Ge10 and Ge11 are recording over 300 million increments in 4 days. The overall issue is virtual tape performance traversing 7840s from local to remote site is effected.
The ge_err_in_pkt_drop counter is the only counter thus far incrementing. Tunnels and circuits between 7840s seem okay
but the 7840 local LAN inbound ports(Ge10 and Ge11) increment the ge_err_in_pkt_drop counter.
So when you state "packet drops are related to pause frames received from peer ge_stat_rx_pause_frms."
Do you mean "ge_err_in_pkt_drop" counts are only of concern if the same 7840 Ge interface also increments
Or do you mean if ge_err_in_pkt_drop counts are only of concern if the sending device's port has incrementing
"ge_err_in_pkt_drop" counts are not a concern if the same 7840 Ge interface also increments
Thank you. We learned a bit more from Brocade/Broadcom Level 3 and it's essentially the same information you stated.
"As observed the "ge_err_in_pkt_drop" counter is the same value as the pause frames received. This is a limitation of an internal component. This counter is deprecated in newer levels.
So, ignore "ge_err_in_pkt_drop" and use rx_pause counter. The "ge_err_in_pkt_drop" will no longer be present in later FOS.
