Please configure NTP server address in the System ---> Time ---> NTP page, and select “Use NTP Server” as clock source in the System ---> Time ---> Manual page.
You can check it on web UI as the following path. Configuration ---> Filtering Data Base And CLI command as below: Switch# fdb Switch (fdb)# show mac-table No    Type     MAC Address        VID   Ports ----  -------  -----------------  ----  --------------- 1     Dynamic  00-1a-80-4a-b8-e7  1     6 2     Static   00-40-c7-aa-bb-cc  1     None,CPU 3     Static   33-33-00-00-00-01  1     1-26,CPU 4     Static   33-33-00-00-00-02  1     1-26,CPU 5     Static   33-33-ff-17-38-fa  1     1-26,CPU 6     Static   33-33-ff-aa-bb-cc  1     1-26,CPU Switch (fdb)# show static-mac Total static MAC address : 0
You can configure Trap Event Severity and Syslog Level to achieve the purpose. Syslog Level: Emerg > Alert > Crit > Error > Warning > Notice > Info > Debug (ex. If you setup syslog level as “Info”, it means all Emerg, Alert, Crit, Error, Warning, Notice and Info related messages will send to syslog server.)
Yes, you can configure different “Privilege Level” for different users. If the user’s privilege level is lower than group’s privilege level, the user doesn’t have permission to modify the group’s setting. CLI command: (Suppose to create a new account/password “TESTER” with user privilege level 5, and the user only has permission to modify the System group settings. ) Switch# account Switch(account)# add 5 TESTER TESTER Switch(account)# exit Switch# privilege Switch(privilege)# group system 5 Note: For the example, all groups’ need to have higher privilege level than 5 except the “System” group.
No, it only can press HW “RESET” button about 10 seconds to reset the switch to factory default.
Please try to clear your browser’s cache/cookies and then restart it again.
Suggest configure as below:
  • Port Type as “C-port” and Egress Rule as “Trunk” for Uplink port.
  • Port Type as “C-port” and Egress Rule as “Access” for Downlink port(Here it means PCs or can’t recognize VLAN tag devices).
CLI command: (Suppose port 1 is uplink port, port 2~10 are downlink ports.) Switch # vlan Switch (vlan)# port-type 1 c-port Switch (vlan)# egress-rule 1 trunk Switch (vlan)# port-type 2-10 c-port Switch (vlan)# egress-rule 2-10 access
You can try to configure the “Access Management Configuration” to restrict IP address range and protocol. Web UI path: Security ---> Access Management ---> Configuration CLI command: (Suppose only allow IP address 192.168.3.30~192.168.3.50 can access the switch by HTTP/HTTPS protocol .) Switch# access Switch(access)# add 1 ipv4 192.168.3.30 192.168.3.50 web
From Web UI, you can use “Firmware Selection” to achieve the purpose. Web UI path: Maintenance ---> Firmware ---> Firmware Selection ---> to press “Active Alternate Image” button. CLI command: Switch# firmware Switch (firmware)# swap
You can change VLAN ID in the IP configuration page   faq CLI command: (Suppose to change management VLAN to VLAN10) Switch # ip Switch (ip)# mgmt-vlan 10 Please note that you may also need to change the management port’s PVID to the same as management VLAN ID or send packets with the same as management VLAN ID tag that can manage the switch.
Execute this command “reboot“ Switch# reboot
U can check “Help” button on Web UI , it is usually in the upper right corner Every feature has it’s mapping help page , there are some basic explanation .

  1. U can enable STP/RSTP/MSTP (this is an example for setting RSTP on port 2~8 ) :
Switch(stp)# version rstp Switch(stp)# p-mode 2-8 enable Switch(stp)# sh pconf   Port  Mode      AdminEdge AutoEdge  restrRole restrTcn  bpduGuard Point2point ----  --------  ------------------  ------------------  --------------------- Aggr  Disabled  Disabled  Enabled   Disabled  Disabled  Disabled  Enabled   Port  Mode      AdminEdge AutoEdge  restrRole restrTcn  bpduGuard Point2point ----  --------  ------------------  ------------------  --------------------- 1     Disabled  Disabled  Enabled   Disabled  Disabled  Disabled  Auto 2     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 3     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 4     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 5     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 6     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 7     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 8     Enabled   Disabled  Enabled   Disabled  Disabled  Disabled  Auto 9     Disabled  Disabled  Enabled   Disabled  Disabled  Disabled  Auto 10    Disabled  Disabled  Enabled   Disabled  Disabled  Disabled  Auto Switch(stp)#        
  1. U can enable loop-protect (this is an example for enable loop-protect )
Switch# loop-protect Switch(loop-protect)# mode enable Switch(loop-protect)# show config Loop Protection   : Enabled Transmission Time : 5 Shutdown Time     : 180   Port  Mode      Action            Transmit ----  --------  ----------------  -------- 1     Enabled   Shutdown          Enabled 2     Enabled   Shutdown          Enabled 3     Enabled   Shutdown          Enabled 4     Enabled   Shutdown          Enabled 5     Enabled   Shutdown          Enabled 6     Enabled   Shutdown          Enabled 7     Enabled   Shutdown          Enabled 8     Enabled   Shutdown          Enabled 9     Enabled   Shutdown          Enabled 10    Enabled   Shutdown          Enabled   Note :
  1. Do not enable STP/RSTP/MSTP and loop-protect on the same port .
  2. Do not enable loop-protect on bone port (it meaning not directly connect to user )

Used switch to ping some popular Web site on Internet , like Google . Then check it will response or not . Switch# diag Switch(diagnostic)# ping www.google.com PING server 74.125.23.99, 56 bytes of data. 64 bytes from 74.125.23.99: icmp_seq=0, time=60ms 64 bytes from 74.125.23.99: icmp_seq=1, time=50ms 64 bytes from 74.125.23.99: icmp_seq=2, time=60ms 64 bytes from 74.125.23.99: icmp_seq=3, time=70ms 64 bytes from 74.125.23.99: icmp_seq=4, time=70ms Sent 5 packets, received 5 OK, 0 bad Switch(diagnostic)# For above case :  this switch link to internet well In fail case , user will got response like this : Switch# diag Switch(diagnostic)# ping www.google.com *** Invalid IP address: www.google.com Switch(diagnostic)# And if switch can’t connected to internet , Pls check it’s IP and DNS server correct or not !? If there existed DHCP server , u can enable DHCP , then switch will get IP and DNS server automatic : Switch# ip Switch(ip)# dhcp enable Switch(ip)# sh Configured      Current --------------- --------------- DHCP Client          : Enabled IP Address           : 192.168.3.79    192.168.6.70 IP Mask              : 255.255.255.0   255.255.255.0 IP Gateway           : 0.0.0.0         192.168.6.250 VLAN ID              : 1               1 DNS Server           : 0.0.0.0         168.95.1.1 DNS Proxy            : Disabled
Install some syslog server tool on PC (ex: Tftpd) and enable it . Setting it via Web : Please configure syslog in the “Syslog ---> Configuration” page , like below : Server mode = enable Server Address = 192.168.3.250 (server IP) Syslog Level = Debug U also can setting via CLI: Switch(ip)# Switch#syslog Switch(syslog)# mode enable Switch(syslog)# server 1 192.168.3.250 Switch(syslog)# level 7 Switch(syslog)# sh config Server Mode      : Enabled Server Address 1 : 192.168.3.250 Server Address 2 : Syslog Level     : Debug Switch(syslog)#
