12. Address resolution table

The (A)rt menu is used for creation and editing of Address resolution tables. These tables are used on Channel-to-Node interface, when a complex conversion of the user address space to the MORSE address space is needed. Ethernet and some protocol access modules can use these tables, too. The (A)rt menu allows for editing table items regardless of the purpose to which the table is used.

The size of table Art is limited. Art1 to 4 may contain a total of 252 items. No more than 100 items are recommended to be added to a single Art table. More space can be created in table Art using fw Walrus in the hw M-Server for the MAS function.

The Art table consists of needed amount pairs (d)est + g(w) length 4 + 4 byte. The (d)est is e.g. MORSE address and g(w) is IP address. The MORSE addresses are converted to IP addresses by the table. The content of pairs can be different according to needs. Example:

690F0041 C0A80120
690F0042 C0A80125
690F0072 C0A80114
690F1589 C0A80137

From MORSE main menu type A Enter

Address Resolution Table: (N)o:1
(d)est:00000000 g(w):00000000
(g)et p(u)t (D)elete item
de(f)ault gw
(c)lear
(r)ead all
(q)uit
>>

(N)o :1	— number of table edited (1, 2, 3 or 4)
(d)est: 00000000	— destination address (`dest`) used in the following commands
g(w) : 00000000	— gateway address (`gw`) used in following commands
p(u)t	— adds new item ( `dest` and `gw` ), overwrites when an item with the same dest already exists
(g)et	— for given dest finds the respective `gw`
(D)elete	— deletes the item with given `dest` (if exists)
de(f)ault	— writes `gw` into the `default gw` item (the `default gw` is used for unlisted destinations)
(c)lear	— clears the whole table
(e)dit	— edit mode – the whole table is transferred into Setr and edited or it is directly created in Setr. Then it is written into CU as one unit. See description bellow.
(r)ead	— reads the whole table

type r Enter

Edit Art as one unit

From MORSE main menu type Ae Enter Enter:

Address Resolution Table editor:
ART No 1: 
items: 2
default gw: 00000000 (0.0.0.0        )
dest:    gw:
56509004 C0A86304 (86.80.144.4     192.168.99.4   )

The contents of the table is transferred into Setr. Using the commands (c)lear, (d)est, ga(t)eway, de(f)ault, (g)et, p(u)t, (D)eletemodify the table in Setr similarly as was described above for work in menu A Enter in CU. Using (w)ritetransfer the whole table into attached CU in Art designated by parameter N(o):1.

Similarly the content of table Art1 can be transferred to e.g. Art2 or to other CU. Example:

Read the content of Art3 from distant CU using command (r)ead:

Address Resolution Table editor:
ART No 3: 
items: 1
default gw: 00000000 (0.0.0.0        )
dest:    gw:
11111111 33333333 (17.17.17.17     51.51.51.51    )
(c)lear table (N)o:3
(d)est: 0 ga(t)eway: 0
de(f)ault gateway
(g)et p(u)t (D)elete item
(r)ead (w)rite
(q)uit
690F8001h>

Don’t close the Art menu, redirect to other CU, choice number of table Art table (N)o:4 and write there the content by command (w)rite.

!h0101

690F0101h>N4

690F0101h>w

690F0101h>
ART No 4: O.K.
690F0101h>r

690F0101h>
ART No 4:

default gw: 00000000 (0.0.0.0        )

11111111 33333333 (17.17.17.17     51.51.51.51    )
690F0101h>

It is visible by check (r)ead that the content is written in Art4.
