Important Notice About C2G1x4-xx 10/100/100 and SFP Mini-GBIC Ports
SFP Mini-GBIC uplink ports are used in an either / or configuration with the C2 front panel RJ45 10/100/1000
Mbps 1000BASE-T Fast Ethernet copper ports. If all Mini-GBIC ports are used, four of the RJ45 ports will be
disabled. The maximum number of active ports can be 24 on the C2G124-24, and 48 on the C2G124-48 and
C2G124-48P, in any combination of RJ45s and Mini-GBICs.
Port String Syntax Used in the CLI
Commands requiring a port‐string parameter use the following syntax to designate port type, slot
location, and port number:
port type.unit_or_slot number.port number
Where port type can be:
fe for 100‐Mbps Ethernet
ge for 1‐Gbps Ethernet
tg for 10‐Gbps Ethernet
host for the host port
vlan for vlan interfaces
lag for IEEE802.3 link aggregation ports
Where unit_or_slotnumber can be:
1 ‐ 8 for switch units in a stack
