Getting Started
Thank you for choosing the Cisco Small Business Series Smart Gigabit Ethernet
Switch. The Smart Gigabit Ethernet Switches are cost-effective switching
solutions ideal for small businesses, the network edge, or workgroups within
larger organizations. These easy-to-install, high speed switches offer many of the
same Quality of Service and Security features found in more expensive full Layer 2
managed switches but without their complexity. The Smart Switches offer the
following interfaces:
•The SLM2024 and SLM2048 offer twenty four (24) or forty eight (48)
Gigabit copper ports, with two (2) shared copper or optical (SFP) uplink
interfaces for connecting the switch to the core network.
•The SLM224G, SLM224P, SLM248G, and SLM248P offer twenty four (24) or
forty eight (48) 10/100 copper ports, with two (2) shared Gigabit copper or
optical (SFP) uplink interfaces for connecting the switch to the core
network.
The Smart Switch’s simplified user interface is an intuitive management tool
enabling you to quickly utilize the comprehensive feature-set of the switch,
resulting in a better optimized network. The user interface is a web based
application that uses Microsoft Internet Explorer 6.0 or later, or Firefox 5.0 or later.
Starting the Application
To open the User Interface:
STEP 1 Open a web browser.
NOTE The default IP address is 192.168.1.254. If you have changed the IP address
or are using DHCP to assign it, enter the new IP address instead. The
computer you use for configuration should be on the same subnet as the
Switch.

•Link Aggregation
•LACP
•PoE Power Setting (in SLM224P and SLM248P only)
Port Settings
You use the Port Settings window to display the speed, duplex mode, and flow
control used on specific ports, or use to detect the connection settings used by
the attached device. Use the full-duplex mode on ports whenever possible to
double the throughput of switch connections. Flow control should also be enabled
to control network traffic during periods of congestion and prevent the loss of
packets when port buffer thresholds are exceeded. The Switch supports flow
control based on the IEEE 802.3x standard.

Port Settings window contains the following fields:
•Port — Displays the port number.
•Description — Displays the device port user-defined description.
•Administrative Status — Displays the port admin status. The possible field
values are:
- Up — Indicates the port is administratively enabled.
- Down — Indicates the port is currently administratively disabled.
•Link Status — Defines whether the port is currently operational or non-
operational. The possible field values are:
- Up — Indicates the port is currently operating.
- Down — Indicates the port is currently not operating.
•Speed — Displays the configured rate for the port. The port type
determines what speed setting options are available. Port speeds can only

be configured when auto negotiation is disabled. The possible field values
are:
- 10 — Indicates the port is currently configured at 10 Mbps.
- 100 — Indicates the port is currently configured at 100 Mbps.
- 1000 — Indicates the port is currently configured at 1000 Mbps.
•Duplex — Displays the port duplex mode, can be either Full or Half. Full
indicates that the interface supports transmission between the device and
its link partner in both directions simultaneously. Half indicates that the
interface supports transmission between the device and the client in only
one direction at a time. The Duplex Mode field is configurable only when
auto negotiation is disabled, and the port speed is set to 10M or 100M. The
Duplex Mode field cannot be configured on LAGs.
•MDI / MDIX — Displays the Media Dependent Interface (MDI) / Media
Dependent Interface with Crossover (MDIX) status on the port. Hubs and
switches are deliberately wired the opposite of the way end stations are
wired, so that when a hub or switch is connected to an end station, a
straight through Ethernet cable can be used, and the pairs are matched up
properly. When two hubs or switches are connected to each other, or two
end stations are connected to each other, a crossover cable is used to
ensure that the correct pairs are connected. The possible field values are:
- MDIX — Use for hubs and switches.
- MDI — Use for end stations.
•Flow Control — Displays the flow control status on the port. Operates when
the port is in full duplex mode.
•Port Type — Displays the port type. The possible field values are:
- Copper — Indicates the port has a copper port connection and displays
the copper speed.
- Fiber — Indicates the port has a fiber optic port connection.
•LAG — Indicates in which LAG the port is a member.

•Admin Status — Enables or disables traffic forwarding through the port.
•Current Port Status — Displays the port connection status.
•Reactivate Suspended Port — Reactivates a port if the port has been
disabled through the locked port security option.
•Operational Status — Displays whether the port is currently operational or
non-operational.

supports transmission between the device and the client configured in both
directions simultaneously. Half indicates that the interface supports
transmission between the device and the client in only one direction at a
time.
•Current Duplex Mode — Displays the port current duplex mode.
•Auto Negotiation — Enables Auto Negotiation on the port. Auto Negotiation
is a protocol between two link partners that enables a port to advertise its
transmission rate, duplex mode and flow control abilities to its partner.
