Note: If you configure your 100 Mbps ethernet line for TCPONLY, all IOP assist | |
functions are disabled. |

Communications restrictions apply if any of the following communication functions are required when using the frame relay IOAs, as listed above:
vX.25, Frame Relay, or IPX Protocol
vSDLC protocol, if used to connect to more than 64 remote sites
vCommunications line speeds greater than 64 Kbps and up to 2.048 Mbps for the synchronous data link control (SDLC) or frame relay protocols (bisync is always limited to a maximum of 64 Kbps)
vCommunications line speeds greater than 64 Kbps and up to 640Kbps for X.25

You can use the following data to help you plan for and anticipate performance | |
when merging host tables. The data represents averages of measurements that are | |
taken. The actual time required on your server will be different. |
Three cases were measured:
vSmall
vMedium
vLarge
The results of this test are shown in Table 7.

Running TCP/IP Only: Performance Considerations | ||
Certain configurations of 2838 - 10/100 Mbps Ethernet cards allow you to run the | ||
IOP with only TCP/IP instead of all protocols for better performance. You need a | ||
2838 Ethernet card with either: | ||
v 2810 | IOP | |
v 2809 | IOP (the 2838 must be the only input/output adapter (IOA)IOA on the | |
IOP) |
