![This interface module operates on multiple port densities and operating modes. Each physical port can be extended to have 2 ports of 1 Gigabit Ethernet with the use of Compact-SFP [GLC-2BX-D].](/docs-images/75/72935653/images/1-1.jpg "Each port on Compact-SFP (CSFP) acts as Tx/Rx and connects to GLC-BX-U using single strand fiber. Note GLC-2BX-D CSFP must be connected only to GLC-BX-U.")
1 Configuring 1-port 10 Gigabit Ethernet (1 X SFP+) / 1-port Gigabit Ethernet (1 X SFP) / 2-port Gigabit Ethernet (1 X CSFP) and 16-port Gigabit Ethernet (8 X CSFP) / 8-port Gigabit Ethernet (8 X SFP) The 1-port 10 Gigabit Ethernet (1 X SFP+) / 1-port Gigabit Ethernet (1 X SFP) / 2-port Gigabit Ethernet (1 X CSFP) interface module has 8 ports of 1 Gigabit Ethernet and 1 port of 10 Gigabit Ethernet. This interface module operates on multiple port densities and operating modes. Each physical port can be extended to have 2 ports of 1 Gigabit Ethernet with the use of Compact-SFP [GLC-2BX-D]. Each port on Compact-SFP (CSFP) acts as Tx/Rx and connects to GLC-BX-U using single strand fiber. Note GLC-2BX-D CSFP must be connected only to GLC-BX-U. This interface module has 9 physical ports of 1 Gigabit Ethernet and 1 physical port of 10 Gigabit Ethernet, but with the support of CSFP, it can support a maximum of 18 ports of 1 Gigabit Ethernet.

2 Operating Modes Configuring 1-port 10 Gigabit Ethernet (1 X SFP+) / 1-port Gigabit Ethernet (1 X SFP) / 2-port Gigabit Ethernet (1 X CSFP) IOS Port Numbering, page 3 Suported Features, page 4 Benefits, page 5 Restrictions, page 5 Configuring Interface Module, page 5 Verifying High Priority and Low Priority Counters Configuration, page 8 SADT Mode, page 8 Bandwidth Mode, page 8 Associated Commands, page 13 Additional References, page 13 Operating Modes The interface module supports two operating modes. Full Subscription Over Subscription Note The interface module supports 8 x 1GE + 1 x 10GE mode by default (except the slots 0,1,6, and 9 with XFI Pass through mode). Full Subscription Mode Full subscription operating mode supports the bandwidth equal to the number of ports configured. For example, if you configure 16 X 1GE + 1 X 10GE full subscription operating mode, then the supported bandwidth is 16 Gigabit Ethernet and 10 Gigabit Ethernet. The following are the supported operating modes of Full Subscription: 8 X 1GE + 1 X 10GE 8 X 1GE + 1 X 1GE 8 X 1GE 1 X 10GE Over Subscription Mode Over Subscription operating mode is applicable to 1 Gigabit Ethernet port only. This operating mode always supports 8 GE bandwidth, irrespective of the number of 1 Gigabit Ethernet ports. But, if the total bandwidth 2
3 IOS Port Numbering of 16 or 18 Gigabit Ethernet ports becomes more than 8 Gigabit Ethernet, then it results in low priority traffic drop. For example, if you configure 16 X 1GE + 1 X 10GE over subscription operating mode, then 8G bandwidth is suported for 16 ports of 1 Giagabit Ethernet and 10G bandwidth is supported for 10 Giagabit Ethernet ports. The following are the supported operating modes of Over Subscription: 16 X 1GE 16 X 1GE + 1 X 10GE 18 X 1GE Note In this mode, 10 Gigabit Ethernet physical port slot becomes 2 ports of 1 Gigabit Ethernet with insertion of CSFP. Note By default, the interface module loads in 8 X 1GE + 1 X 10 GE modes (except the slots 0, 1, 6, and 9 with XFI-Pass Through mode. For more information, refer Compatibility Matrix. Traffic is classified as follows: High Priorty Traffic - Has high priority queue This is classified as follows: DMAC=01-80-C2-xx-xx-xx Etype=0x8100, 9100, 9200, 88A8 Cos values=5, 6, 7 Etype=0806 (ARP), 88F7 (PTP) Etype=0x800, TOS 5, 6, 7 Etype=0x8847, MPLS EXP 5, 6, 7 Low Priority Traffic - Has low priority queue IOS Port Numbering The IOS port numbers is different from other typical interface module because of the flexibility of optics choices and operating modes. The IOS port number is even numbered for SFP optics and the additional port on C-SFP insertion is the odd number from the gap as enumerated in the table below.

Table 3: IOS Port Number 10G Face Plate Port SFP+ SFP (1G BW) C-SFP (1G BW) 8 Ten Gigabit Ethernet 0/x/16 Ten Gigabit Ethernet 0/x/16 Ten Gigabit ethernet 0/x/16 and Gigabit Ethernet 0/x/17 Suported Features Supports PTP implementation. PTP is supported on 1G SFP AND 2G CSF. Supports SyncE. Supports both full subscription and over subscription modes. Provides multiple combinations of port density in Full subscription and Oversubscription modes. Provides multiple port densities. 4
5 Benefits Benefits The interface module has more port density. 10 GE port can also operate in 1GE mode. Restrictions You must reload the device after changing mode each time. In XFI Pass through mode, the interface module goes out of service without any mode configuration on slots 0,1,6, and 9. To start the interface module, the supported modes on the slots must be configured before inserting the interface module. Changing the mode second time on an interface module without reload fails. This interface module is only supported on Cisco ASR 900 RSP3 module. 10G SFP+ is not supported for PTP. OTN, Wan Phy, and MACsec are not supported. High Priority Traffic with frame size more than 4500 bytes is not supported for oversubscription mode. COS, EXP, and DSCP fields in frames with values 5, 6, and 7 respectively, are considered as High Priority Traffic for Oversubscription mode than all other control packets.
