To enable IGMP on your Cisco Catalyst 3550 switches, you need to enter the ip igmp command in the interface configuration mode. For example, to enable IGMP on Fast Ethernet port 0/1, you need to enter these commands: Switch(config)#interface fastethernet 0/1 Switch(config-if)#ip igmp
- PIM is used to route multicast traffic between different networks. It allows routers to discover and maintain multicast routes dynamically. To enable PIM on your Cisco Catalyst 3550 switches, you need to enter the ip pim command in the interface configuration mode. For example, to enable PIM sparse mode on Fast Ethernet port 0/1, you need to enter these commands: Switch(config)#interface fastethernet 0/1 Switch(config-if)#ip pim sparse-mode
- MSDP is used to share multicast source information between different PIM domains. It allows routers to learn about active sources from other domains and forward multicast traffic accordingly. To enable MSDP on your Cisco Catalyst 3550 switches, you need to enter the ip msdp command in the global configuration mode. For example, to enable MSDP with a peer router with the IP address 10.10.10.10, you need to enter this command: Switch(config)#ip msdp peer 10.10.10.10
- MVR is used to deliver multicast traffic across different VLANs on a network. It allows switches to forward multicast traffic from a source VLAN to multiple receiver VLANs without replicating the traffic on each VLAN. To enable MVR on your Cisco Catalyst 3550 switches, you need to enter the mvr command in the global configuration mode. For example, to enable MVR with VLAN 10 as the source VLAN and VLANs 20 and 30 as the receiver VLANs, you need to enter these commands: Switch(config)#mvr Switch(config-mvr)#mvr vlan 10 Switch(config-mvr-vlan)#mvr group 239.1.1.1 Switch(config-mvr-vlan)#mvr receiver-vlan 20 Switch(config-mvr-vlan)#mvr receiver-vlan 30
For more information on how to configure multicast features on your Cisco Catalyst 3550 switches, you can refer to this document:
- [Configuring IP Multicast Routing](https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3550/software/release/12-2_55_se/configuration/guide/3550_scg/swmcast.html) Security features
Security features are used to protect the network from unauthorized access, attacks, and threats. Security features include access control lists (ACLs), port security, Dynamic Host Configuration Protocol (DHCP) snooping, Dynamic ARP Inspection (DAI), IP Source Guard, and Private VLANs. To configure security features on your Cisco Catalyst 3550 switches, you need to enter the global configuration mode from the privileged EXEC mode. To enter the global configuration mode, you need to enter the configure terminal command. The prompt for global configuration mode is Switch(config)#. - ACLs are used to filter network traffic based on different criteria, such as source and destination addresses, protocol types, port numbers, and packet markings. ACLs can be applied to interfaces or VLANs to permit or deny traffic. To configure ACLs on your Cisco Catalyst 3550 switches, you need to enter the access-list command in the global configuration mode. For example, to create a standard ACL named 10 that permits traffic from the network 10.10.10.0/24, you need to enter this command: Switch(config)#access-list 10 permit 10.10.10.0 0.0.0.255
- Port security is used to limit the number and type of devices that can connect to a switch port. Port security can prevent unauthorized devices from accessing the network or causing a denial-of-service (DoS) attack. To configure port security on your Cisco Catalyst 3550 switches, you need to enter the switchport port-security command in the interface configuration mode. For example, to enable port security on Fast Ethernet port 0/1 and allow only one device with the MAC address 0000.1111.2222 to connect to it, you need to enter these commands: Switch(config)#interface fastethernet 0/1 Switch(config-if)#switchport mode access Switch(config-if)#switchport port-security Switch(config-if)#switchport port-security maximum 1 Switch(config-if)#switchport port-security mac-address 0000.1111.2222
- DHCP snooping is used to prevent rogue DHCP servers from offering invalid IP addresses to clients on the network. DHCP snooping can also prevent DHCP starvation attacks that exhaust the IP address pool of a legitimate DHCP server. To configure DHCP snooping on your Cisco Catalyst 3550 switches, you need to enter the ip dhcp snooping command in the global configuration mode. For example, to enable DHCP snooping on VLAN 10 and trust Fast Ethernet port 0/1 as a DHCP server port, you need to enter these commands: Switch(config)#ip dhcp snooping Switch(config)#ip dhcp snooping vlan 10 Switch(config)#interface fastethernet 0/1 Switch(config-if)#ip dhcp snooping trust
- DAI is used to prevent ARP spoofing attacks that manipulate the ARP cache of devices on the network and redirect traffic to malicious hosts. DAI can validate ARP packets by checking their source MAC and IP addresses against a trusted database that is built by DHCP snooping or static entries. To configure DAI on your Cisco Catalyst 3550 switches, you need to enter the ip arp inspection command in the global configuration mode. For example, to enable DAI on VLAN 10 and trust Fast Ethernet port 0/1 as an ARP trusted port, you need to enter these commands: Switch(config)#ip arp inspection vlan 10 Switch(config)#interface fastethernet 0/1 Switch(config-if)#ip arp inspection trust
- IP Source Guard is used to prevent IP spoofing attacks that use forged source IP addresses to bypass security policies or launch DoS attacks. IP Source Guard can filter traffic based on the source IP and MAC addresses of packets and allow only traffic that matches a trusted database that is built by DHCP snooping or static entries. To configure IP Source Guard on your Cisco Catalyst 3550 switches, you need to enter the ip verify source command in the interface config
