Overview
About the Lantronix C3230 Series
The C3230 Series (C3230 and C3231) is the Gigabit managed NID module for the Lantronix ION chassis. It marks the demarcation point of a Carrier Ethernet service, converting a customer's 10/100/1000Base-T copper port to fiber while giving the operator visibility and control over the circuit. It is MEF 9, 14 and 21 certified. Beyond the IEEE 802.3ah Link OAM found on Fast Ethernet NIDs, it adds IEEE 802.1ag Service OAM and ITU Y.1731 for end-to-end service monitoring.
Each card has one RJ-45 copper port and one or two empty 100/1000Base-X SFP slots, so optics are chosen per link. Service features include 802.1Q VLAN and double tagging across 4096 VIDs, 802.1p, IPv4 TOS/DiffServ and IPv6 traffic class QoS classification, bandwidth profiling and 10,240-byte jumbo frames, with an 8K MAC table. Remote loopback, Far-End-Fault, Link Pass Through, DMI optical monitoring and copper cable diagnostics support troubleshooting.
Management is via the card's own IP address, in-band through a local peer, or the ION Management Module. Supported interfaces are web, CLI, Telnet, SSH, SNMP v1/v2c/v3 and Focal Point, plus a USB port for initial setup. Operating environment depends on the chassis, with the card rated 0°C to 50°C.
Key capabilities
- Service OAM
- IEEE 802.1ag and ITU Y.1731 Service OAM alongside 802.3ah Link OAM for end-to-end Carrier Ethernet monitoring.
- One or two SFP slots
- Choose one 100/1000Base-X SFP slot (C3230-1040) or two (C3231-1040) and fit optics to each link.
- MEF 9, 14 and 21
- Certified to MEF 9, 14 and 21 for Gigabit Carrier Ethernet services; Lantronix publishes each certificate on the product page.
- Layer 2 and 3 QoS
- Classifies traffic by 802.1p, IPv4 TOS/DiffServ and IPv6 traffic class, with bandwidth profiling per service.
- Flexible management
- IP-based remote management or in-band via a local peer, with SSH, SNMPv3, RADIUS and a management VLAN.
How to choose the right C3230 Series part number
Both cards have one 10/100/1000Base-T RJ-45 port and ship with empty SFP slots. C3230-1040 has a single 100/1000Base-X SFP slot for a standard copper-to-fiber NID hand-off. C3231-1040 has two SFP slots, which suits designs that need a second fiber port, for example to chain or dual-home the service. Choose 100Base-X or 1000Base-X SFPs, multimode or single-mode, to match the provider's fiber plant.

C3230 Series FAQ
What is the difference between the C3230-1040 and C3231-1040?
The C3230-1040 has one empty 100/1000Base-X SFP slot, and the C3231-1040 has two. Both have one 10/100/1000Base-T RJ-45 port and the same OAM, VLAN and management features.
How does the C3230 differ from the C2220?
The C3230 uses 100/1000Base-X SFP slots for Gigabit fiber and adds IEEE 802.1ag Service OAM and ITU Y.1731. The C2220 has a 100Base-FX fiber port and Link OAM. Both are MEF 9, 14 and 21 certified.
Are SFP modules included with the C3230?
No. Both C3230 part numbers ship with empty SFP slots, so you choose 100Base-X or 1000Base-X SFPs, multimode or single-mode, for the fiber type and distance required.
What management options does the C3230 support?
IP-based remote management on its own address, in-band management by a local peer, or the ION Management Module, using web, CLI, Telnet, SSH, SNMP v1/v2c/v3 or Focal Point.
What is the maximum frame size on the C3230?
10,240 bytes, so jumbo frames pass through the NID. The card's MAC table holds 8K addresses, and it supports 802.1Q VLAN and double tagging across 4096 VIDs.
