Known Issue:
1.
[ACL]
A filtering rule with discard source action will always filter packets regardless of
source MAC or destination MAC.
2.
[STP]
When using three different spanning tree protocols (RSTP+MSTP+MRSTP) on the
whole network, the network will loop.
[Workaround]
- Use the same STP protocol on the whole network.
3.
[IPv6]
Port movement of IPv6 address is not supported currently.
[Workaround]
- Waiting for MAC address timeout
- Clear MAC address for the host entry.
4.
[LACP]
When RSTP is enabled with ring topology, LACP can't be activated at the same
ports.
[Workaround]
- Change the LACP to Static Trunk.
5.
[VLAN]
Configure private VLAN with follow features are not recommend:
- VLAN stacking
- VLAN mapping
- Remote port mirroring
[Symptom]
- Private VLAN behavior may be affected.
6.
[VLAN]

- Port isolation function may affect.
7.
[Diagnostic]
The cable diagnostic tolerance is +-10M length.
8.
[Log]
Alignment error packet will count in CRC error counter.
9.
[Routing]
Switch learn 1K hosts entry already, after clear all ARP entry, switch may need
3~4 minutes to re-learn all host entry.
[Symptom]
- Before all hosts re-learn back to switch, some of hosts will not be able to forward by
VLAN routing.
[Condition]
- 1K hosts learn on the switch, then reboot device.
- 1K hosts learn on the switch, then enter clear ARP table.
10.
[LLDP]
LLDP management address will not refresh immediately.
[Condition]
(192.168.1.1) Switch1------Switch2 (192.168.1.2)
- Switch1 and Switch2 enable LLDP.
- Switch1 can know the Switch2 management IP is 192.168.1.2 via LLDP.
- Switch2 changes ip address to 192.168.1.3
- Both 192.168.1.2 and 192.168.1.3 entry will display on the Switch1 LLDP page.
[Workaround]
Waiting for 30 seconds then it will automatic refresh.
Stacking Know Issue:
1.
[Flow Control]
Flow control does not support traffic cross stacking devices.
[Condition]
PC1------Slot1---Slot2----PC2
