Device LLDP PVID mismatch

Several access devices, such as APs and IP Phones, support LLDP and that is very convenient for discovery and troubleshooting. However, these devices may include the locally configured PVID (the untagged VLAN) in their outgoing LLDP frames. This may result in some warning log messages in the switch. Continue reading

Comware7: Configuration commit delay

In the old days it was quite common to schedule a device reboot e.g. 5 min ahead when ‘tricky’ remote device changes had to be performed over an in-band connection such as SSH/telnet. In case the config changes provided the desired result, the reboot would be cancelled. When the changes would have resulted in a lost management connection, the reboot would have reverted the device state to the previous config (assuming no ‘save’ was done).

Comware 7 now has a similar feature but without the device reboot, so this is an online ‘swap’ of the configuration without the reboot delay. Continue reading

The write-up can be found on:

Hope you’ll all like the solution and find it useful.

Comware 7: QOS Queue Management Profile qmprofile enhancement

On the 5900 platform, any change in the interface queue configuration had to be configured at the interface level.

When a network administrator wants to use FCoE, the interface queue configuration is used by DCBX to configure the server CNA with the proper number of Queues and weights. If multiple servers need to be connected, each server-facing interface had to be configured. And even when interface range commands can be used, the actual interface configuration was getting more complicated due to the number of additional commands per interface.

With the R2416 release of Comware7, the concept of Queue Management Profiles has been introduced to simplify this configuration. This is similar to the way e.g. the existing 12500 series are doing the queue configuration.
