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 format....

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 subinterfaces...

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...

My company is in the process of building a small scale network architecture strictly for testing purposes. We have a DMZ area that contains 2 load balancers and 1 web server. The web server is a SunFire 280 and has two gig e nics. They want to cable ...

Hi,has anyone tried to configure a dlsw+ peer which is terminated in a vrf ??? Is there any other solution to combine both technologies ??Carsten

I have the problem that a Mainframe OSA-2 will not transmit data in any of 3 modules of WS-X6148-RJ45V in a CAT6513, running IOS 121-13.E6.Just about any other Network card/OS (ie 3COM NIC or Intel/UNIX OS) work without issue.A 10mb OSA-2 will work i...

HII need to configure a 7505/4 to receive TCP/IP connections on behalf on the m/f. We will have a cip2 connected to the esconn channel on the m/f. Has any body got any good weblinks showing good practice design and configuration for this. I am lookin...

Hi Experts.My Customer is a Bank with a two-tiered WAN: 100 small remote sites directly connected (leased lines) to HQ.There is also a Medium Regional Site with redundant WAN connection to the HQ. Remote sites and Regional Site have a DLSw peering to...

hi,i need to know if DLSw "local-switching" is supported beetween 2 (or more) Ethernet interfaces on the same router.This is for resolve situation of stations on two differents VLANs and an as400 on another VLAN.Another possibility may be to have onl...
