Ethernet Routing Switch 8600 module fundamentals
The Ethernet Routing Switch 8600 8630GBR module is an R module and
supports:
•
256 000 IP routes
•
64 000 MAC records
•
Release 4.1 and earlier: 16 000 in R mode
Release 5.0 and later: 32 000 in R mode
The 8630GBR module supports R and M mode.
8648GTR module
The 8648GTR module provides 48 10/100/1000BASE-TX ports that
use 8-pin module (RJ-45) connectors. Each port operates either at 10
Mbps, 100 Mbps, or 1000 Mbps (1 Gbps) and supports the IEEE 802.3ab
standard. Distances of up to 100 meters are obtainable with CAT 5
unshielded twisted pair (UTP) cable. The following figure shows the
8648GTR.

8648GTR module
The 8648GTR module is not supported in the 8003 chassis with Release
4.1 or later.
On the 8648GTR module, ports operating at 100 Mbps support a
maximum frame size of 9188 bytes. Ports operating at 10 and 1000 Mbps
support 9600 byte frames.
The 8648GTR module ports supports the IEEE 802.3 1998 Clause 28
Auto-Negotiation standard. Each port can operate in full- or half-duplex
mode. When a port is connected to another device that also supports the
IEEE 802.3 1998 Clause 28 Auto-Negotiation standard, the two devices
negotiate the highest possible data rate and the duplex mode of operation.
The 8648GTR module further supports Custom Auto-Negotiation
