did you see this issue only at this command?
instead write terminal you can use "show configuration snapshot"
There you can filter like for only seeing parts of the config:
> show configuration snapshot ip vlan ?

Thanks a lot!
The terminal hanged and kept hanged even after 10 minutes. However I was able to get configurations by using
but why it doesn't show configuration at terminal ?
When I used following both command at terminal returned nothing, I was also looking if I can use this command at console and it work but not on terminal, then is there any security scenario or something which causes hang in terminal?
and
Both commands return nothing at terminal but work fine at Console port.
Kindly help me to find reason!
Regards,

Did you use SSH or Telnet? Do other show command work, or only this both?

I used telnet and ssh both, both ways terminal hanged but when I use these two commands "write terminal" and "show configuration snapshot" and the control never comeback until around 10 minutes even the session might have already ended.
I assumed if there is some security behind that we can use these commands at console but not on terminal and to make work these commands at terminal we might have to enable something, perhaps.

no, there is no security with this command if you use the same user (f.e. admin).
Have you created other user with read-write all and tried with this one?
which release?

Its MTU setting's problem, seems like MTU setting is not properly configured at both end. But being newbee I have no idea about to change settings etc.
Can anyone help?
I tried
I received dots, such as

What else I should check ?
Best Regards,

So you haven't tested SSH/Telnet via local network direct at the switch? There MTU can't be a reason.
At the switch site you can change the mtu from default 1500 with the following two commands:
Code: Select all
vlan 10 mtu-ip 1400
icmp type 3 code 4 enable
You can check it with the following command (if10 is name of your used ip interface)
But if there is an other connection (f.e. VPN) than you have to change it at the source (router/firewall).

Well I was telnet and ssh to switch but seem like even after changing MTU size it is not responding, I check ping with different packet sizes but
Code: Select all
[root@alu ~]# ping 173.241.19.126 -f -s -d 100
PING 100 (0.0.0.100) 0(68) bytes of data.
..........................................................
Code: Select all
[root@alu ~]# ping 173.241.19.126 -f -s 1500
PING 173.241.19.126 (173.241.19.126) 1500(1528) bytes of data.
