Hello,
I am IT teacher at a middle school in Nuremberg, Germany. We have in our school 5 VLANs, 4 Switchtes, 1 L3 switch and 1 router.
2 months ago the old L3 switch (Catalyst 3550-12T) is broken. In the short term I've borrowed a Catalyst 3750G-24, so that the network continues to function. Now a SG 300-10 switch was purchased. This should be configured the same as the 3550-12T or 3750-24G.
The network looks like this (there are much more PCS than in this image):
VLAN ID | VLAN Interface | DHCP | DHCP-pool |
1 | 192.168.0.1 /24 | no DHCP | no DHCP-pool |
10 | 192.168.10.1 /24 | 192.168.10.2 (MS Server 2008) | 192.168.10.20 – 192.168.10.49 |
20 | 192.168.20.1 /24 | 192.168.10.2 (DHCP-relay) | 192.168.20.20 – 192.168.20.99 |
30 | 192.168.30.1 /24 | 192.168.30.2 (ubuntu-server, FOG) | 192.168.30.20 – 192.168.30.199 |
40 | 192.168.40.1 /24 | 192.168.40.254 (Router) | 192.168.40.20 – 192.168.40.99 |
The DHCP server in VLAN 30 is also a FOG server. The Fog server images all PCs in school. PCs in VLAN 10, 20 and 30 boot from PXE. The MS Server in VLAN 10 has been configured by the DHCP options 66 and 67.
The Catalyst 3750G-24 routes the multicast, but the SG 300-10 I do not have the option of using the commands
- ip multicast-routing distributed
- ip pim sparse-dense-mode
to work and must configure igmp. I'm having problems with the igmp-configuration on the SG 300-10. Therefore, I have uploaded the configuration of the 3750G-24 and the configuration of the SG 300-10 (without ACL). I would greatly appreciate help or advice when configuring igmp.
Thank you in advance and best regards
Markus
