Re: What is the definition for "ge_err_in_pkt_drop" on Brocade 7840 GE port

Hello,

 

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.

Re: What is the definition for "ge_err_in_pkt_drop" on Brocade 7840 GE port

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

"ge_stat_rx_pause_frms" ?  

 

Or do you mean if ge_err_in_pkt_drop counts are only of concern if the sending device's port has incrementing

"ge_stat_rx_pause_frms"?

Re: What is the definition for "ge_err_in_pkt_drop" on Brocade 7840 GE port

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.
