DHCP and Switch Question

RouterOS General

Hello

I have one question. I have one RB750G-2HnD.
I tried to use the Switch all Ports and activate the DHCP Server.

But without success. I set all ether1 as master.

[admin@MikroTik] >> interface ethernet print
Flags: X - disabled, R - running, S - slave

NAME MTU MAC-ADDRESS ARP MASTER-PORT SWITCH

0 RS ether1 1500 D4:CA:6D:29:86:36 enabled none switch1
1 S ether2 1500 D4:CA:6D:29:86:37 enabled ether1 switch1
2 RS ether3 1500 D4:CA:6D:29:86:38 enabled ether1 switch1
3 S ether4 1500 D4:CA:6D:29:86:39 enabled ether1 switch1
4 S ether5 1500 D4:CA:6D:29:86:3A enabled ether1 switch1

then I enabled the DHCP Server on ether1.

[admin@MikroTik] >> ip dhcp-server print
Flags: X - disabled, I - invalid

NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP

0 I dhcp1 ether1 192.168.10.1 dhcp_pool1 3d

But I dont get any IP Address. Why?

Its the first time that I use the Switch Menu. Normaly I use the Bridge but now I need wire speed :wink:

Is that an ‘I’ (invalid) preceeding the dhcp server name? If so, you should find out why.

[admin@MikroTik] >> ip dhcp-server print
Flags: X - disabled, I - invalid

NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP

0 I dhcp1 ether1 192.168.10.1 dhcp_pool1 3d

Why is there a relay entry of 192.168.10.1?

dhcp-relay

[admin@MikroTik] > ip dhcp-relay print
Flags: X - disabled, I - invalid

NAME INTERFACE DHCP-SERVER LOCAL-ADDRESS

0 relay1 ether1 192.168.10.1 192.168.10.1

and the DHCP Server

[admin@MikroTik] /ip dhcp-server> print
Flags: X - disabled, I - invalid

NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP

0 dhcp1 ether1 192.168.10.1 dhcp_pool1 3d

my PC is connected to ether3

So 192.168.10.1 is the dhcp server for your network?

Set the relay and src. address settings to 0.0.0.0.

the the DHCP Server gets invalid

[admin@MikroTik] /ip dhcp-server> print
Flags: X - disabled, I - invalid

NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP

0 I dhcp1 ether1 dhcp_pool1 3d

Do you have an ip is the same segment on ether1
