Table 9 lists physical and logical density maximums for the E120 router and the E320
router. The following notes are referred to in Table 9:
1.
Wire rate indicates the port density that supports maximum (wire-rate)
performance. Oversubscribed indicates the port density possible if you are willing
to accept less than wire-rate performance by oversubscribing the available fabric
bandwidth.
2.
With a 120 Gbps configuration on the E120 router, you can install up to 6
combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots
numbered 0-5. You can install a maximum of 6 active ports and 6 redundant ports
at any time.
With a 100 Gbps fabric configuration on the E320 router, you must install the ES2
10G Uplink LM, the ES2 10G LM, or the ES2 10G ADV LM in either of the E320 router
turbo slots (2 and 4). When the ES2 10G Uplink LM, the ES2 10G LM, or the ES2 10G
ADV LM is installed in slot 2 or slot 4, you cannot install another line module in slot
3 or slot 5. In this case, you can only install the ES2 4G LM in slots 0–1 and 6–11;
therefore, the maximum number of ports and the forwarding performance per
chassis is reduced for the IOAs that pair with the ES2 4G LM.
With a 320 Gbps fabric configuration on the E320 router, you can install up to 12
combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots
numbered 0-5 and 11-16. You can install a maximum of 12 active ports and 12
redundant ports at any time.
