When two Supervisor Engine Vs are present in a Catalyst 4507R and Catalyst
4510R, all four uplinks are active on both Primary (active) and Secondary
(standby) supervisor engines by default, or two uplinks will be active in a
nonredundant configuration. This limits access to slot 10 on the Catalyst 4510R
to ports 3 and 4 only. You can only use the 2-port Gigabit Ethernet switching
module (WS-X4302-GB) or the Access Gateway Module (WS-X4604-GWY) in
slot 10 (flex-slot), when a Supervisor Engine V is used.
10-Gigabit Ethernet Uplink Ports
The 10-Gigabit Ethernet uplink ports operate in full-duplex mode only, and are
only on the WS-X4516-10GE and WS-X4013+10GE. These ports use the
hot-swappable 10GBASE X2 optical transceivers. The X2s have SC connectors
to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable.
On a Catalyst 4510R with a Supervisor Engine V-10GE, the user has the option
to use either four Gigabit Ethernet uplinks using SFPs or two 10-Gigabit Ethernet
uplinks using X2s. The user also has the option of using the Gigabit Ethernet and
10-Gigabit Ethernet uplinks simultaneously. With this option, the tenth slot can
only support the WS-X4302-GB switching module. On a Catalyst 4507R, the user
can use the Gigabit Ethernet uplinks and 10-Gigabit Ethernet uplinks
simultaneously.
When two Supervisor Engine V-10GEs are present in a Catalyst 4510R or
Catalyst 4507R switch, or two Supervisor Engine II-Plus 10GEs are present in a
Catalyst 4507R, one X2 uplink is active on both the primary (active) and
secondary (standby) supervisor engines by default, or two uplinks will be active
in a nonredundant configuration.
SFP Ports
Gigabit Ethernet SFP ports operate in full-duplex mode only and are present on
the WS-X4013+TS, WS-X4516-10GE and WS-X4013+10GE supervisors, as
well as some switching modules. These ports use the 1000BASE-SX,
1000BASE-LX, Cisco Coarse Wave Division Multiplexing (CWDM ) SFPs,
1000BASE-T SFP, and 1000BASE-ZX SFP. SFP connectors vary with interface
type and may use multimode fiber (MMF), single-mode fiber (SMF) cable, or
copper Ethernet cables.
