Note
When you congure or update the settings of your switch, make sure to click
to save the updates to the start - up conguration le.
The start - up conguration le remains when you restart or reboot the switch, but not after you reset the switch to
its factory default settings.
Set up access VLANs
VLANS are typically used on large networks to create multiple broadcast domains, but they can also be used to segregate network
trafc. For example, video trafc can be part of one VLAN, and other network trafc can be part of another .
1. Go to Advanced > VLANs > Conguration .
8
AXIS D8248 Managed PoE++ Switch
Setup examples
2. Under Global VLAN Conguration , enter the VLANs you want to create to the Allowed Access VLANs eld. For example, if
you enter , 1, 1 0 - 13, 200, 300, the following VLAN IDs will be created: 1, 1 0, 1 1, 12, 13, 200 and 300.
3. T o assign a created VLAN ID to a given port under P ort VLAN Conguration , enter the ID to the P ort VLAN eld.
4. Click Apply .
Reserve an IP address based on MAC address

2. Click Add New P ool .
3. Enter a name for the pool, for example 00:0 1:0 2:03:04:05, and click Apply . No spaces are allowed in the name.
4. T o access the pool settings, click the added name.
5. In the T ype drop - down menu, select Host .
6. Enter other required settings, such as IP address, Subnet Mask and Default Router .
7. In the Client Identier drop - down menu, select MAC .
8. In the Hardware Address eld, enter the MAC address of the device.
9. Click Apply .
Set a P oE schedule
If you have a certain time frame where you want the switch to provide P oE, for example, to your cameras, it can be useful to create a
P oE schedule and assign it to one or more P oE ports. Y ou can create up to 16 P oE schedule proles.
T o create a P oE schedule:
1. Go to Advanced > P oE > Schedule Prole .
2. In the Prole drop - down menu, select a number for the prole.
3. Change the default prole name as needed.
4. T o specify when you want P oE to switch on, select hours ( HH ) and minutes ( MM ) in the Start Time drop - down menu.
5. T o specify when you want P oE to switch off, select hours ( HH ) and minutes ( MM ) in the End Time drop - down menu.
- If you want to use the same schedule for all days of the week, select the start and end times on the W eek Day
row marked with an asterisk ( * ).
- If you want to use the same schedule for certain days of the week only , select the start and end times for
selected days on the respective W eek Day rows.
6. Click Apply .
T o assign the created P oE schedule to one or more P oE ports:
1. Go to Basic > Basic Settings > P oE > P ower Management .
2. Under P oE P ort Conguration in the P oE Schedule drop - down menu, select the number of the specied P oE schedule
prole.
- If you want to assign the same prole for all ports, select the prole number on the P ort row marked with an
asterisk ( * ).

AXIS D8248 Managed PoE++ Switch
Setup examples
- If you want to assign the same prole for certain ports only , select the prole numbers for selected ports on the
respective P ort number rows.
3. Click Apply .
Check connection status via P oE auto checking
Y ou can use P oE auto checking if you want to periodically check the connection status between your switch and the P oE enabled
network device connected to it. If, during auto checking, the network device does not respond to the switch, the switch will
automatically restart the P oE port the network device is connected to.
T o enable auto checking via the topology view:
1. Go to Basic > T opology View .
2. T o open the Dashboard console of your switch, click the switch icon.
3. Click P oE Cong .
4. In the P oE Auto Checking drop - down menu, select Enable .
T o congure the auto checking parameters:
1. Go to Advanced > P oE > Auto Checking .
2. In the Ping IP Address eld, enter the IP address of the device that is connected to the port you want to assign auto
checking for .
3. Enter the other needed parameters, for example:
- P ort : 1
- Ping IP Address : 192.168.0.90
- Startup Time : 60
- Interval Time (sec) : 30
- Retry Time : 3
- Failure Action : Reboot Remote PD
- Reboot time (sec) : 15
4. Click Apply .
Use the console port
The switch has a serial console port that allows you to manage the switch through the command - line interface.
1. Connect a console cable to the console connector on the switch.
2. Connect the console cable to the USB port on your computer .
3. On your computer , open a teminal emulator to manage the switch.
Use these port settings:
- Baud rate: 1 15200
- Stop bits: 1
- Data bits: 8

Create redundant links between switches for network redundancy
If network redundancy is required, you can create redundant links between switches using spanning tree conguration.
Example:
In this example, the switches AXIS D8248 (1), AXIS T8508 (2), and AXIS T85 16 (3) are connected by a redundant link, and no extra
VLANS. If any of the uplinks between the switches should fail, the redundant link is activated and provides network connectivity .
Device name Model name
CIST ports
Switch - 0 1 AXIS D8248
5 1, 52
Switch - 0 2 AXIS T8508
9, 1 0
Switch - 03 AXIS T85 16
17, 18
T o create a redundant link on each switch’s web page:
1. Go to Advanced > Spanning T ree > Conguration > Bridge Settings .
2. Under Basic Settings in the Protocol V ersion drop - down menu, select RSTP , and click Apply .
3. Go to Advanced > Spanning T ree > Conguration > CIST P ort .
4. Under CIST Normal P ort Conguration , make sure that STP Enabled is selected for the switch’s ports as follows:
- Switch – 0 1: ports 5 1 and 52
- Switch – 0 2: ports 9 and 1 0
- Switch – 03: ports 17 and 18
5. Click Apply .
Note
If you want to make sure that a certain port is used as a primary communication link, enter P ath Cost for that port under
CIST Normal P ort Conguration . If not specied, the switch selects the port automatically . For example, if you want to use
port 17 as the primary communication link, enter P ath Cost value 1 0 to port 52 and P ath Cost value 50 to port 18.
