The S1700 managed switch provides swappable Small Form-Factor Pluggable
(SFP) optical modules for GE optical fiber connections and swappable Small
Form-Factor Pluggable plus (SFP+) optical modules for 10GE optical fiber
connections. The length of optical fibers can be selected according to the
transmission distance.
The S1700 managed switch supports the Spanning Tree Protocol (STP), Rapid
Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP)
(supported only by fully-managed switches) to prevent loops and provide
rapid switchover.
The S1700 managed switch supports port-based MAC address filtering to
prevent hackers from attacking user terminals or networks by forging MAC
addresses.
The S1700 managed switch supports Remote Authentication Dial In User
Service (RADIUS) authentication, 802.1x authentication, and MAC address
authentication to prevent unauthorized users from accessing the enterprise
network.
The S1700 fully-managed switch supports the DHCP snooping function, which
generates user binding entries based on MAC addresses, IP addresses, IP
address leases, VLAN IDs, and interface numbers of users. This function
protects networks against common attacks such as bogus IP packet, man-in-
the-middle, and bogus DHCP server attacks.
The S1700 managed switch can classify traffic based on 802.1p fields, VLAN
IDs (only fully-managed switches), MAC addresses (only fully-managed
switches), and ACL (only fully-managed switches).
Each port of an S1700 managed switch supports up to 8 queues (each port of
S1728GWR-4P supports up to 4 queues). In addition, the S1700 managed
switch supports weighted round robin (WRR), Priority Queuing (PQ), WRR +
PQ (only S1720 and S1730S), Weighted Deficit Round Robin (WDRR) (only
S1720 and S1730S), and PQ + WDRR (only S1720 and S1730S) queue
scheduling algorithms to effectively ensure high-quality voice, video, and data
services.
Some models of the S1700 use natural heat dissipation, which avoids power
consumption and noise of fans.
NO TE
The following switch models have fans and use forced air cooling: S1700-52GFR-4P-

S1720X-32XWR-E, S1720-28GFR-PWR-4P, S1720-52GFR-4P, S1720-52GFR-PWR-4P,
S1730S-S24P4S-A, S1730S-S24P4S-MA, S1730S-S48T4S-A, S1730S-S24T4X-A, S1730S-
S48P4S-A, and S1730S-H48T4S-A.
The chip changes to the power saving mode when a service port is idle (no
connected device is detected).
