support user hierarchical management and password protection. they support DHCP
Snooping, VBAS, and CPU protection mechanism.
High strength thunder-proof capability: ZXR10 2600 series switches are Richer 8
earthquake resistant. They can run normally in terrible environment.
2.3 Rate limit for ports of different categories
ZXR10 2600-EI series L2 Ethernet switches have rate limit for ports of different
categories. Highly efficient multiple leaky bucket algorithm is adopted. Unicast uses one
leaky bucket and other traffic flows use the other leaky bucket. Each leaky bucket uses
different bandwidth. Controlling policy is quite complete. Unknown unicast and MAC
controlling frame can be restricted besides ordinary broadcast, multicast and unicast. On
one hand, it can protect user bandwidth against appropriation and on the other hand, it
can effectively control network viruses which may cause invalid broadcast traffic.

4.1.2 Console Port
The Console port is connected to the Com port of a computer for the initial configuration
management of the switch.
4.1.3 FE Port
ZXR10 2609 provides nine 10/100M fast Ethernet ports, 2609-FU provides eight 10/100
M fast Ethernet ports and a fixed 100M optical port (multiple mode 2KM, single mode
15KM, and single mode 40KM can be selected). All ports support automatic MDI/MDI-X
operations. Switches can be connected to PCs, servers, hubs or other switches with
straight-through or crossover cables.
Table 1 Maximum Cable Length
Cable Type Maximum Cable Length

Each port supports IEEE802.3x self-adaptation. Therefore, the most suitable
communication mode (half duplex or full duplex) and data rate (10 Mbps or 100 Mbps)
can be selected automatically. (The connected equipment must also support this
feature.) If the equipment connected to these ports does not support self-adaptation, the
ports will adopt the peer rate, but the default communication mode will be half duplex.
The rate control is subject to a granularity of 64 K. The ingress can be configured with
any of the following policies: all frame restricted, multicast frame and flooded unicast
frame restricted, multicast frame (including broadcast) restricted, and broadcast frame
restricted.
Each port of the 2609, 2609-FU has a LNK/ACT indicator. If the indicator is on, the link
is activated. If the indicator blinks, data transfer is going on.

protocol process and data driving. The data forwarding is automatically completed. The
management plane processes data configuration and notifies the current operation
status. The configuration is basically completed under an interactive environment.

IGMP Snooping function, and QoS policy. The system has reserved interfaces for the
convenience of future development.
4.3.2 Data Processing Procedure
4.3.2.1 Data Exchange Process
For a switch, data exchange actually means forwarding data from port to port. After
receiving a data frame, the switch sends it to the proper port according to the destination
MAC address in the frame header.
The switch completely depends on an important internal data structure CAM table
(namely, the MAC address table) to select ports according to the destination MAC
address. The CAM table contains information of MAC address and port identification
(such as port ID) at least. When a packet reaches a port, the switch will check the
destination MAC address in the address table and display the destination address of the
port. If the destination address is an inbound port, the packet will be discarded or filtered
because it is addressed to the local lot. If the destination address is another port, the
packet will be forwarded to the port and queued until it is output. If the destination
address is not in the address table, the data frame will be sent to all ports other than the
source port. If the source address of the packet is not found in the address table, the
source address and the inbound port ID will be recorded to determine the subsequent
forwarding.
A layer 2 Ethernet switch exchanges data in the following three steps:
•Address learning: The switch receives a data frame at one port and checks the
CAM table according to the source MAC address of the data frame. If the MAC
does not exist in the CAM table, the switch will add related information (including
the source port ID) of the MAC to the CAM table. In this way, address learning is
completed.
•Forwarding decision: After address learning, the switch will search the CAM table
according to the destination MAC address of the data frame. If the MAC is found,
the switch will send the data frame to the send queue of the corresponding port
according to the search result (including the source port identification). If the MAC is
not in the address table, the switch will send the data frame to all ports other than
the source port. This process is called flooding.
•Data forwarding: After making the forwarding decision, the switch will forward the
data frame by means of the hardware.

4.3.2.2 Flow Direction of VLAN Data Packet
In consideration of the network security and convenient management, the VLAN
technology is adopted in the current network deployment. The following describes the
flow direction of data packets in the VLAN. The VLAN processing procedure is as
follows:
•Data frame inbound: The switch classifies inbound data frames according to their
VLAN identification (VID): data frames without VID into one category and those with
the same VID into another category. The switch forwards or discards a data packet
according to the VID. Meanwhile, the switch can assign a VID to a frame without
any labeling or a frame labeled as priority.
•VLAN tag: If a data frame has no VID, the switch will assign a VID to it and insert it
into the frame header. This process is called “Label VLAN”. The switch handles
packet forwarding and fills the VLAN of the data frame or the identification field of
the priority information through this process. The administrator can set the priority to
select the type of VLAN and the VID. The default setting of the switch includes the
IP subnet information, the network protocol, the MAC address, and the inbound port
of the data frame.
•Filtering: The process verifies whether the destination address and the source
address are in the same VLAN.
•Forwarding: The switch either forwards a data frame or discards it according to the
information of the VLAN database.
•Learning: The switch checks the source address of the data frame and VLAN
classification information and records them in the forwarding database.
The port mode of ZXR10 2600 series is divided into access mode and trunk mode. The
port mode determines the data output form, namely, whether the VLAN data packet is
output directly or output with the Tag removed after the switch makes a forwarding
decision.
As far as the encapsulation of data packets is concerned, ZXR10 2600 series are the
same as most Ethernet switches. That is, when an untagged data packet reaches a port,
the switch encapsulates a tag for the packet according to the PVID of the port and then
determines the VID according to the tag. Finally the switch searches the destination site
of the data packet in the same VLAN. If the destination MAC address is found, the data
packet will reach the destination. If the destination MAC address is not determined or
found, the data packet will be broadcast in the same VLAN or directly discarded.
