Introducing the GLC1320G-55 1.1 GLC1320G-55 Overview The GLC1320G-55 is a Gigabit Ethernet Line Card with 20 SFP slot connector slots for fiber-based SFP (mini-GBIC) transceivers (16 for SFP transceiver and 4 for CSFP/SFP). It connects through fiber-optic cables to other Ethernet switches that support fiber connections (like the FSG1100HN, GS2200-8 or FMG3024/3025) located at the subscriber’s premises.

Subnet based VLAN allows you to group traffic into logical VLANs based on the source IP subnet you specify. When a frame is received on a port, the GLC1320G-55 checks if a tag is added already and the IP subnet it came from. The untagged packets from the same IP subnet are then placed in the same subnet based VLAN.

Alarm LED An ALM (alarm) LED lights when the GLC1320G-55 is overheated, the voltage readings are outside the tolerance levels, a fan fails, or another alarm with a severity level of MAJOR or CRITICAL occurs.

IGMP multicast servers. IGMP Statistics The GLC1320G-55 records the number of active users in an IGMP multicast channel (multicast group). The GLC1320G-55 also records IGMP message statistics on a per port basis to ease management and troubleshooting. GLC1320G-55 User’s Guide...

Chapter 1 Introducing the GLC1320G-55 IGMP Message Rate Limiting The GLC1320G-55 can limit how many IGMP message packets a subscriber can send per second. This prevents subscribers from flooding the multicast server. Static Multicast Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify.
Chapter 1 Introducing the GLC1320G-55 Anti-IP Address Spoofing With DHCP snooping, the GLC1320G-55 records which IP addresses are assigned on each port. The GLC1320G-55 drops packets from a device using a different IP address. Anti-MAC Address Spoofing The GLC1320G-55 checks to make sure the MAC addresses of the devices connected to the subscriber ports are not the same as MAC addresses of devices connected to the Ethernet network.
