I always have problem determining the DRAM and flash of the myriad of IOS and this 2950 running a 12.1(9)EA1 is giving me a headache. Show version: ------------------------------------------------------------ Cisco Internetwork Operating System Software IOS (tm) C2950 Software...

Ugh, what does the abovementioned line do? Cisco explanation is: "Allows a user to select the interface whose address will be used as the source address for TFTP connections" What in the world does it mean? How is this gonna affect my switch, which is not the interface mentioned...

Hi All, when md5 is enabled for NTP, what does it do exactly? How does the routers know each other's key?

Tried to mrtg a 7206 running MPLS but was unable to. Since MPLS was applied only to the E1 lines, the MRTG was unable to graph these interfaces. Error messages were: " WARNING: Could not match host:'snmpread@174.0.1.2:' ref:'Name' key:'Se4/4\:4' ERROR: Target[174.0.1.2_se4_0_0][_IN_] '...

Does anyone have an idea why does this mean? 12:14:42 %PAGP-5-PORTTOSTP:PORT 2/28 joined bridge port 2/28 12:14:25 %PAGP-5-PORTFROMSTP:PORT 2/28 left bridge port 2/28 Does this mean that the port is "flapping"? Or changing from forwarding->blocking->forwarding?

For switches in VTP client mode, if i were to apply access lists to the vlans, will the ACL work?

What does ip route-cache do for a switch (i.e. 3548) in my vlan1?

Hi, is there any good freeware syslogs analysing tools out there?

How do you secure your syslog server? I am in the midst of setting up a syslog server (easy part), but how can i secure it? (hard part)

The kiwisyslogd 7.0.3 does not seem to be able to log or display the syslogs from my 2900XL even though a sniff shows that the NMS is receiving the syslogs...is there any hidden issues?

Other than having 2 links between 2 switches with one in blocking due to spanning tree + uplinkfast turned on (suppose to up the standby link in 1-5 minutes), is there other L2 redundancies (instead of STP) can i implement?

What would be a better idea: Spanning the vlan across different switches or avoid spanning vlan across switches (especially when there is only one user in the vlan that is spanned across a different switch? Is spanning used only when the different switches are located physically apart?

Does anyone turn on UDLD? Will UDLD increase the CPU utilization by alot?

Questions about uplinkfast: For switches with uplinkfast, if the root port goes down, the "standby" link (which is previously down due to spanning tree) goes up within 1-5 seconds. If the root port comes back up, will it do a "preempt" similar to HSRP and cause the...

Does anyone know how can i simulate an E1 link between my 2 2610s with an E1 card each? Is it as simple as just a cross RJ45 terminated UTP cable?

I have a bunch of 3548s each connected to a 4003 via dot1q trunk. VTP pruning is OFF. The 3548s are vt clients while the 4003 is the server. The scenario is that at the 4003, i had prune vlan 200 at trunk interface 3/1 which is connected to switch 3548-2. Does this mean that vlan 200 will no...

Is there any differences between the two other than the fact that the "traditional" ACL is easier to create than VACLs.
