Cisco NIM-ES2-4 and Cisco NIM-ES2-8 Ports
The following sections describe the port numbering and port types on the service modules:
Port Numbering
The Ethernet ports are numbered left to right, top to bottom. The port numbering scheme to configure the
ports on the Cisco NIM-ES2-4 and Cisco NIM-ES2-8 includes the port type (such as
gi
or
gigabitethernet
for Gigabit Ethernet), and the switch port number. If you are not using the NIM-ADPTR, the slot number is
always 0.
For example, to configure Gigabit Ethernet slot/subslot/port, the interface configuration command would be:
Router(config)#
interface gi 0/1/0
Port Types
The following sections describe the port types on the NIM modules:
•
10/100/1000 RJ45 Ports, on page 4
•
Cisco NIM-ES2-4 and Cisco NIM-ES2-8 LEDs, on page 5
All Cisco NIM-ES2-4 and Cisco NIM-ES2-8s, use RJ-45 connectors to provide Gigabit Ethernet (GE)
connections.
10/100/1000 RJ45 Ports
You can set the 10/100/1000 RJ45 ports for speed and duplex autonegotiation in compliance with IEEE
802.3ab. (The default setting is autonegotiate.)
When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises
its own capabilities. If the connected device also supports autonegotiation, the Cisco NIM-ES2-4 and Cisco
NIM-ES2-8 port negotiates the best connection (that is, the fastest line speed that both devices support and
full-duplex transmission if the attached device supports it) and configures itself accordingly. In all cases, the
attached device must be within 100 meters (328 feet).
All 10/100/1000 RJ45 ports on the Cisco 8-Port Layer 2 Gibabit Ethernet NIM with POE can provide power
to IEEE 802.3at-compliant, IEEE 802.3af-compliant, and Cisco prestandard POE device. Power over Ethernet
(PoE) devices are Cisco IP phones, Cisco access points, and some Cisco switches. PoE, formerly referred to
as inline power, is available only on the Cisco 8-Port Layer 2 Gibabit Ethernet NIM form factors supported
by Cisco modular access routers.
The below table provides information on Cisco NIM-ES2-4 and Cisco NIM-ES2-8 port speed and duplex
mode.
Table 2: Port Speed and Duplex
Explanation
Port Function
The operating speed of the switch port. You can choose Auto (autonegotiation) if the connected
device can negotiate the link speed with the switch port.
The default settings are:
• Auto for the external 10/100-Mbps Fast Ethernet ports
• Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports
