Your production setup can be impacted, if you wants to change ip address of switch in production hours . And you might loss access to switch as well.
If switch is connected in HA having both active and passive switch or active -active switch then , there is a possibility to change ip address of switch in production hours . Remove HA cable between switch ...

When a link fails, a directly connected switch removes that port's MAC associations from its MAC table. This usually causes the switch to simply re-learn the removed MAC addresses, temporarily flooding them before that learning takes place.
However, a switch that isn't directly involved in the failed link can't know whether the port it has associated with a ...

If it is layer3 switch and fortigate firewall and switch is connected on L3 interface means . Use "sh ip interfàce brief command
This command will display all interface status on switch . You will have visibility of IP subnet of interface connected to fortigate firewall
In case if firewall is connected with L2 switch then " show mac -address&...

You normally would just overwrite it with e. g.:
vlan 1 ip address 10.10.10.11/8
But if you stay on the same subnet, the switch will complain:
The IP address (or subnet) 10.10.10.11/8 already exists.
If this is the case (you want to stay in the same subnet and just change the IP address inside this subnet), then you'll have to delete the previous IP ...

Intially when PC wants to send packet to destination . PC runs ANDing process and decided whether destination is on same networks or different networks .
If same networks means
Packet is send to connected layer2 switch . L2 switch won't understand destination ip address . Instead of ip address switch understand mac -address . With reference to destination ...

When there is no Configuration configured on managable cisco switches . Cisco switches it's self acts like unmanaged switches .
So you can induct or de-induct switches in networks without any issue . But there is risk of inducting unmanaged switches in setup there is possibility of no loop avoidance mechanism in networks.

My sugestion is to configure switch virtual interfaces(SVI) in core switch for each Vlan . And enable inter-Vlan routing by using command "IP Routing" After enabling inter-Vlan routing all vlan will communicate to each other , Now Configure access-list accordinglly to restrict traffic among Vlans accordinglly to your business requirements . Further ...

For Communication between different subnets packet has to reach router or layer3 devices to process this packet . If another networks is directly connected then forwards packets on basis of ARP table . If destination is on another networks means forwards packet to next hops on basis of route entry Configured on network .
However layer2 device cannot ...

Both 3650 layer3 switch acts as layer2 devices . Natting should done on fortigate firewall . A default route should Configured in firewall pointing towards gateways of ISP .
So nat translation happen in firewall . Frame outbound security policy for internet access .
Souce as :LAN subnet
Destination as : ANY
Action : allow
Services : Https (or others)

Even if you aggregate links (recommended!) you will still not exceed 1Gb per session. I have tried this for Video editing. For file transfer however you can get the aggregate speed by breaking up the file before transfer. In other words a zip file may take 5 hours to transfer but if you have 4 links configured correctly and transfer the files unzipped you ...
