How to update the firmware

For details, please refer to the "Yamaha LAN Monitor User Guide" and the Web GUI help menu.

1. Connect the SWR2311P-10G and the computer with a LAN cable.
   Please connect to a port of SWR2311P-10G set as VLAN1.
2. Start the Yamaha LAN Monitor.
3. Select the SWR2311P-10G to be updated in the tree view.
4. Click the [Web GUI] button on the device detail view.
   With the factory settings, the username and password are not specified, so entering a username and password would be unnecessary in that case.
5. Select [Management] -> [Maintenance] -> [Update firmware], then click the [Next] button on "Update firmware from PC."
6. Click the [Select a file] button, then select the downloaded and decompressed firmware file with extension .bin.
7. Click the [OK] button.
8. Click the [Execute] button.

Wait until completing the update. SWR2311P-10G will automatically restart and become ready to use.

Fixed Bugs

• A bug was fixed that caused the system sometimes to reboot if the CPU usage ratio increased after receiving a portion of the IGMP packet.
• A bug was fixed that sometimes returned unwanted IGMP reports if an IGMP report was received from a multicast router port.
• A bug was fixed that sometimes stopped multicast streams from being forwarded correctly if a LAN/SFP port associated with a logical interface is linked up/down with IGMP/MLD snooping.
• A bug was fixed that sometimes caused unwanted log events to be output if an IGMP snooping group registration was deleted.
• A bug that sometimes prevented authentication when a guest VLAN was enabled during MAC authentication was fixed.
• A bug was fixed that resulted in rebooting if an invalid LLDP frame was received.
• The possibility of rebooting was eliminated after specifying the “send from” command for the mail notification function.
• A bug that prevented using the following commands to make revisions via an SSH connection was corrected.
