Low number of VLANs on CE5810

Issue Description

ON CE5810 i am unable to configure vlan 4064 as the maximum VLAN number seems to be 4063. This happens altough the CE should support all 4094 VLANs (according to the specifications).

Solution

This happens becasue the last 30 VLANs are reserved for Control Plane traffic and cannot be assigned to service traffic. As a conclusion the CE supports all 4094 VLANs but has the final 30 of them reserved for protocol traffic.

Handling Process

FAQ-Why Ping Packets Especially Large Ping Packets Are Lost Sometimes?

This problem is caused by the CPU protection mechanism. The CPU protection mechanism processes ICMP packets as follows:

The software limits the rate of ICMP packets.
The icmp rate-limit { total | interface interface-type interface-number [ to interface-number ] } threshold threshold-value command limits the rate of ICMP packets on each GE interface to 20 pps and on the device to 100 pps by default. When the number of ICMP packets sent by an interface every second exceeds the rate threshold, the system delivers an ACL. The ACL discards all the ICMP packets with the MAC address as the device’s MAC address. After two minutes, the device is restored. This process continues. You can run the undo icmp rate-limit { total | interface interface-type interface-number [ to interface-number ] }} command to cancel rate limiting.
The system limits the rate of ICMP packets sent to the CPU.
The rate limit of ICMP packets sent to the CPU is 128 kbit/s. Assume that the packet size is 1024 bytes. Only 16 packets can be sent to the CPU within 1s, that is, a packet is sent every 62.5 ms. If a packets is sent at the rate grater than 62.5 ms, the packet is discarded. Assume that the packet size is 64 bytes. Only 256 packets can be sent to the CPU within 1s, that is, a packet is sent every 4 ms.

How to obtain the reference documents for an V200R013C00SPC100 Hot Patch upgrade On Huawei OSN1500/3500/7500

Procedure

l   Obtain the XXXX hot patch version description file.

l   Obtain the related release notes and check whether the version of the board software to which the patch is applicable is the same as the actual version of the board software.

To query the NE software version, run the :ver; command.

To query the board software version, run the :cfg-get-bdverinfo:bid; command.

l   Check whether the board type for the patch matches the actual board type.

To query the board type, run the :cfg-get-phybd; command.

Result Verification

All the reference documents are obtained.

Huawei Optix OSN1500/3500/7500 Hot Patch Upgrade Guide

1.1 Upgrade Notes for Versions

This document applies to upgrading a V200R013C00 NE.

1.2 Upgrade Methods

1.2.1 Hot Patch Package

The Huawei OptiX NG-SDH products of V100R008 and later versions support the hot patch package function, and support the DC of the V200R008C00 or later versions.

The hot patch package, which is of the NE level, is added to the OSP V100R010 (corresponding to the OptiX NG-SDH V100R008 and later versions). The hot patch package description file (PKG) forms a logical package, and therefore patches can be installed on all the boards on an NE.

1.2.2 Patch Upgrade Method

In the case of the optical network products, you can use the following methods to perform a patch upgrade:

l   Hot patch package loading.

Board-level hot patch loading: This document mainly describes the hot patch package loading by using the DC tool. For the board-level hot patch loading, see the OptiX NG-SDH Hot Patch Upgrade Guide, which is available from the following path on http://support.huawei.com: Documentation > Optical Network > NG SDH > NG-SDH products > Technical Guides > Upgrade Guide > OptiX NG-SDH Hot Patch Upgrade Guide-20120625-A.

Does AC6605 automatically assign channels and adjust signal strength?

Issue Description

Customer installed multiple AP’s at a site.  He noticed that channels are not being assigned automatically, and had to assign channels manually on 200+ AP’s.  Also the signal strength was not being adjusted dynamically causing some devices to drop connections because the devices were trying to connect to multiple AP’s due to high signal strength.

Alarm Information

none

Handling Process

we reported to R&D and they provided with new version of software.
customer was using V2R2, and we upgraded to V2R3 and issues were resolved.

Root Cause

we tried to turn off certain AP’s in the room, and connection was stable.  customer was having trouble with Apple devices particuarly.

Suggestions

previous version of software had issues with assigning channels and adjusting signal strength.
version V2R3 resolved the issue.

Abnormal Traffic Generated on MPUs of the USG9100 firewall

Issue Description

An MPU of the USG9100 has two LAN interfaces: LAN0 and LAN1. The two interfaces are in initial state. They are not modified or configured and have no link connected. Currently, LAN0 is in normal state, and LAN1 is not connected to a network cable but has data traffic generated sometimes.

Handling Process

Contact Huawei experts for analysis. It is know that the USG9100 of SPC700 has solved this fault. LAN1 on the MPU is used for testing during the production and cannot function as a service interface. The rate of LAN1 is not zero, which does not affect services. Some traffic is generated during the test, which does not affect services. You can solve this problem by upgrading the USG9100 version to SPC700.

Root Cause

Run the following command:
<USG>reset counters GigabitEthernet 1/0/1
Then observe the interface status. After a short period of time, check the interface status. Data traffic is still generated.
This is probably related to the processing mechanism of the USG9100, which is a software fault.
