Comware

Hello,
We deploy video stream by comware switches.
However, on the interfaces of a switch (5510), I have a lot of lost packages.
For video it is problematic.
On the attached image, you will have an overview of the network topology.
Why do I have packages deleted on interfaces 1/0/4, 1/0/6, and Ten 1/0/25?
I don't have one on the Ten 1/0/28 interface.
I activated the "burst-mode enable" command but nothing helps.
Here is the result of the command:

<SW>display packet-drop interface gig 1/0/4
GigabitEthernet1/0/4:
Packets dropped due to full GBP or insufficient bandwidth: 6328369
Packets dropped due to Fast Filter Processor (FFP): 0
Packets dropped due to STP non-forwarding state: 0

<SW>display packet-drop interface gig 1/0/6
GigabitEthernet1/0/6:
Packets dropped due to full GBP or insufficient bandwidth: 235369
Packets dropped due to Fast Filter Processor (FFP): 0
Packets dropped due to STP non-forwarding state: 0

<SW>display packet-drop interface ten 1/0/25
Ten-GigabitEthernet1/0/25:
Packets dropped due to full GBP or insufficient bandwidth: 2944092
Packets dropped due to Fast Filter Processor (FFP): 0
Packets dropped due to STP non-forwarding state: 0

<SW>display packet-drop interface ten 1/0/28
Ten-GigabitEthernet1/0/28:
Packets dropped due to full GBP or insufficient bandwidth: 0
Packets dropped due to Fast Filter Processor (FFP): 0
Packets dropped due to STP non-forwarding state: 0

On the 5510 switch there are cameras plugged in and the result is the same, there are dropped packets.
The multicast streams are in one vlan and the unicast streams of the cameras are in another vlan.

Can you help me solve this problem?

thanks you

Regards

Hi,

Could you please share the display version output from the device?

Hi,

It seems the device is running on latest software. Generally GBP Full bandwidth issue get resolve after enabling the burst mode but its already implemented.

1. Can you please check physical connectivity between interfaces 1/0/4, 1/0/6, and Ten 1/0/25 and end devices.
2. Please upgrade the NIC driver on conencting end devices.
3. If still problem persist then capture packets or log a ticket with support.

Thanks!

Hi,

Has my solution helped you resolve the query or do you need more assistance?

Thanks!

Hello,

Thank you for your reply.

I have checked the connection on the cable and the drivers for the network cards are up to date. Is it possible to add more memory to the port buffers?
There is available memory.

Regards,

i have same issue with hp 10500 (7.1.045, Release 7183) but i did not found command burst-mode 

any idea what is solution 

Hi,

Can you please try like this:

[HPE-10500] burst-mode enable chassis <chassis number> slot <slot number>

But there are possibility that some of the Line card wont support this command.

Thanks!

thanks , i tried before but burst-mode  not recongized command 

Hi,

There are some series card's doesn't support this command.

Also.I believe the device is running on latest software version.

Thanks!

Hello. I have this problem. I have enabled the following commands on my core switch (HP 10508):

system-view
burst-mode enable chassis 1 slot 1
burst-mode enable chassis 2 slot 1
burst-mode enable chassis 1 slot 2
burst-mode enable chassis 2 slot 2
burst-mode enable chassis 1 slot 3
burst-mode enable chassis 2 slot 3

As you can see, we have an irf cluster consisting of two chassis.

After doing this, all the problems related to 1 Gbps have disappeared, no packet drops outbound and inbound associated to card supporting 1 Gbps interfaces..

But We have 4 slots with ten-gigabitethernet. Irf interfaces belong to these slots, as well as firewalls, synergy, etc.

Many packets drops are found on these interfaces and I don't know how to avoid them. I know packet drops are normal on irf interfaces, but I'm worried because many of packet drop bursts are related to firewall interfaces (Check Point firewalls in cluster mode).

These bursts affect snmpget queries and icmp on my network.

Is there another mechanism to avoid these bursts in slots that do not support "burst mode"?

Hello @JUANTRON ,

Is it a 10gig module?

Can you share the product number 'JXXXX" of 10gig module and chassis?

Is chaasis on latest software version, because sometimes packet drop issues might be others?

Also check if there are no layer 1 issues.

Thanks!

I can't apply "burst mode" feature in the following cards:

HP A10500 16-port 10-GbE SFP+ SC Module JC628A (BOARD TYPE: LSU1TGS16SC0)

HPE 10500 16p 1/10GbE SFP+ SF Mod JH193A (BOARD TYPE: LSUM2TGS16SF0)

But "burst mode" is applied in the following cards:

HP A10500 48-port Gig-T SE Module JC618A 

HP 10500 16p GbE SFP/8p GbE Cmbo SE Mod JC763A 

My two chassis are:

HP A10508 Switch Chassis JC612A

There are no layer 1 issues.

Can I apply cut-through to avoid packet drops? And, how?

"cut-through enable" command is not recognized (irf cluster mode)
