With the new IBM hosts z990, there are changes in IO subsystem (30 LPAR max, logical channel subsystem,...)I understand that the z990 LPAR number are now identified by 2 digits.We have 75xx CIP routers connected to our different zOS systems via Escon...

I just upgraded my C7206 router to IOS 12.1(21) recently. I configured Standby IP on the Fastethernet interface (note that there is no secondary router in place yet). Very frequent ICMP packets drop happens when I try to use the workstations to ping ...

I have two 3810v, both with 12-1(3a) software and I can not do a show running-config nor a write term command. I am seeing numerous buffer and memory failures, which usually points to an IOS issue. However, I am using this old of IOS to support VoH...

We have NCR 9800 mainframes, which are currently connected over a leased line...talking NCR proprietary protocol.We have a requirement now, to connect them over IP.I would like to know if the mainframe box supports any network controller cards to sup...

In my environment I have a thousand of remote DLSw+ peers configured with circuit-count and costs. In a datacenter I have 8 routers to terminate DLSw+ connections. Working only with DLSw+ all remote peers establish the circuits in a balanced mode bet...

Here are my queries - 1.Could the tunneling protocols...DLSw, STUN , BSTUNbe used to tunnel just any protocol, or is it specific to IBM SNA , NetBIOS? we are interested in connecting NCR mainframe systems over IP.These NCR systems talk NCR proprietar...

I just install a network based on layers of access (to WAN), DLSw and CSNA. When we start the tests some remote devices start a DLSw circtuits and SNA traffic with no problems, but other devices (SDLC) on remote sites start a DLSw traffic but can't s...

Hi. I have a device that can talk SNA only over the DIX/Ethernet2 frame format. For this reason, it cannot communicate via Ethernet transparent bridging with our mainframe OSA Express, which requires SNA to ride the 802.3/802.2 Ethernet frame forma...

Hi. I have a 7206 router connected with FE to a Catalyst 6509, via 802.1Q trunking. Two VLANs. The router supports DLSW to remote sites, and the switch transports SNA traffic to the router with transparent bridging through one of the FE subinterfac...

I did post this under the LAN switching topic, but it occured to me maybe there's a more "SNA-specific" answer. We are presently migrating off Token Ring, replacing it with switched Ethernet (all-Cisco network). In the process, we've hit a roadblock....

Hello, Main Office(MO) has cisco3660 and PIX515, Remote Office(RO)has either pix or a cisco router to connect to MO via VPN. We want to build an identical datacenter which is connected to MO with direct line(100mb). Data replication is not a proble, ...

HiI have a 7505 with two CIP cards in and a 4port token ring card (amongst other things). The 7505 will have 2 escon connections to the mainframe. I wish to implement CLAW load balancing across the 2 CIP cards, although the clients will use one IP ad...
